Identifying these suspect smells on your car

Most vehicles start out with a “new car smell,” but there are other specific odors that motorists should never ignore. Identifying these suspect smells early on can help car owners be car care aware and avoid the hassle and expense of an unexpected breakdown, says the Car Care Council.

“Unusual smells can be the sign of serious, and potentially costly, trouble for your vehicle. By acting quickly and making necessary repairs, you’ll be able to breathe easy knowing there is no harmful damage to your car,” said Rich White, executive director, Car Care Council.

The Car Care Council recommends a sniff test of your vehicle to identify any unusual smells, including the following six warning signs:

1.  The smell of burnt rubber could be slipping drive belts or misplaced loose hoses that might be rubbing against rotating accessory drive pulleys. Do not reach in if the engine compartment is hot.

2.  The smell of hot oil could mean that oil is leaking onto the exhaust system. To verify the leak, look for oil on the pavement or smoke coming from the engine area.

3.  The smell of gasoline is likely the sign of a gas leak in some area of the vehicle such as a fuel injector line or the fuel tank. Any smell of fuel can result in a possible fire hazard, so immediate attention should be given.

4.  The sweet smell of syrup may be a sign that your car is leaking engine coolant from a leaky component related to the car’s cooling system. Do not open the radiator cap when it is hot.

5.  The smell of burning carpet could be a sign of brake trouble and a safety hazard. Have your brakes checked right away, especially if this smell is happening during normal driving conditions.

6.  The smell of rotten eggs is never a good one and, if you smell it coming from your vehicle, it could mean a problem with your catalytic converter not converting the hydrogen sulfide in the exhaust to sulfur dioxide properly. This smell can also be attributed to a poor running engine, causing the catalytic converter to become overloaded and fail due to meltdown.

“When you smell any peculiar odor, you should not ignore it. Instead bring your vehicle to a professional service technician that you trust to get an informed opinion on the nature of the odor,” concluded White.

Family Finances and the Environment

According to the nonprofit National Institute for Automotive Service Excellence (ASE), motorists can help the environment and their own finances by incorporating a few good practices. Regular vehicle maintenance and better driving habits are two simple ways any car owner can go “green” — both for the environment and one’s own wallet.

Here are a few specific, easy-to-implement tips from ASE:

  • Keep the engine running at its peak performance. A misfiring spark plug can reduce fuel efficiency as much as 30 percent. Replace filters and fluids as recommended in the manual. A well-tuned engine pollutes less and uses less. Moreover, neglected engine performance problems can cause costly repairs over time
  • If you do your own repairs, be a good steward of the environment. Dispose of engine fluids and batteries properly. A single quart of used motor oil can pollute thousands of gallons of water. Antifreeze poured on the ground can poison wildlife and household pets. Check around at local repair facilities to see if they accept used fluids and parts, or call your local government agencies for information on proper disposal and recycling.
  • Keep tires properly inflated and aligned. If your air pressure is low, you force the engine to work harder and burn more gasoline. Tires that are misaligned also make your vehicle work harder. Consider, too, that poorly maintained tires wear out faster, which means more discards have to be scraped, recycled, or sent to the landfill.
  • If weekend car tinkering is not your idea of fun, find a dependable ASE-certified technician. Ask friends for recommendations. Check the reputation of the repair shop with your local consumer group. Check out the technician’s specific credentials. ASE-certified auto technicians are tested for specific skills and knowledge in national exams, such as engine performance, brakes or suspension.
  • Have your vehicle’s air conditioning system serviced only by a technician qualified to handle and recycle refrigerants. Older systems contain ozone-depleting chemicals, which could be released into the atmosphere through improper service. If you have used any over-the-counter remedies such as system sealants or self-service refrigerants, let the technician know prior to servicing the vehicle.
  • Avoid speeding and sudden accelerations. Both habits guzzle gas and put extra wear-and-tear on your vehicle’s engine, transmission, steering and suspension system, and other components. Use cruise control and anticipate traffic patterns ahead. As a side benefit, your brakes will last longer, too.
  • Consolidate daily errands to eliminate unnecessary driving. When waiting for friends or family, shut off the engine. Park in a central location at the shopping center, and walk from store to store, rather than drive from one end to the other.
  • Remove excess items from the vehicle. Less weight means better mileage. Remove that roof-top luggage carrier after vacations to reduce air drag.

Treat Your Engine to be Nice

We all know that the Golden Rule reads, “Do unto others as you would have them do unto you.” Well, here’s your chance to implement that rule and enhance the life and value of your car at the same time. Over the last decade or so we’ve learned that breathing dirty air can be hazardous to our health. The same logic applies to the engine in your car, SUV, or light truck or van. Keeping the inside of your engine clean will keep it healthy, longer, and will enhance its value if you decide to sell or trade it. MANN+HUMMEL Purolator Filters is one of the largest suppliers of filters for cars and trucks, so they know a thing or two about treating engines nice, and their spokesman Kevin O’Dowd offers the following advice: “Internal engine parts are made to extreme levels of precision. For instance, hydraulic valve lifters are manufactured to tolerances as stringent as one ten thousandths of an inch (0.0001”). So even tiny particles can interfere with the engine’s operation, and can cause damage to piston rings, engine bearings, and other critical engine components.” Filters are the guardians of your engine, and can do a very effective job of preventing potentially damaging particulates from getting to where they don’t belong. The three key filters protecting your engine are its oil filter, its air filter, and its fuel filter. Here’s what you need to know about each type. Oil Filters During the course of normal engine operation particles can collect in the engine oil.

These particles can include bits of carbon resulting from combustion, pieces of engine gaskets and seals that can erode over time, and even small bits of metal that can flake/break off of various engine parts. O’Dowd suggests that an oil filter can capture and safely hold such particulates, but the protection depends on the quality of the oil filter and the frequency with which it is changed. “The two key characteristics of oil filters are efficiency and capacity,” explains the Purolator expert. “Efficiency describes the ability of the filter to capture particulates of a given size. For instance, Purolator Classic oil filters are 97.5 percent efficient, meaning that they have the ability to capture 97.5 percent of particulates 20 microns in diameter or larger. A micron is a millionth of a meter, or about one-thousandths of an inch. And our top-of-the-line PureONE oil filters are 99.9 percent efficient.” “The other key measure of an oil filter’s performance is capacity, which is a measure of the amount of contaminants an oil filter can hold before becoming completely blocked and directing unfiltered oil to the engine’s moving parts. While unfiltered oil is slightly better than no oil at all, it surely offers substantial opportunity for irreparable engine damage. Our Purolator PureONE oil filters have a capacity of 13 grams, which is the equivalent of 31 standard-size paper clips.” In addition to efficiency and capacity, O’Dowd recommends that you also consider other features when selecting an oil filter. Things like the quality and configuration of the pleated filtering medium and the integrity of the housing, end plates, seals, and valving are all features that separate quality oil filters from inexpensive and inefficient filters. Air Filters Automotive engines need air flow for combustion. And we all know that the air, especially on our highways, can contain all kinds of particulates – soot, bits of tire rubber, and all manner of natural materials, like pollen, bits of leaves, and much more. All of these materials can be harmful to your car’s engine, and must be carefully and efficiently filtered out before air reaches your engine’s combustion chamber. O’Dowd advises that the same parameters, efficiency and capacity, that define an oil filter’s effectiveness, also apply to engine air filters.

A significant difference, explains O’Dowd, is found in the impact of clogging. As an air filter gradually collects contaminants, it steadily chokes off the flow of air entering the engine. The result, explains our Purolator expert, is reduced engine power and efficiency, which can make the engine harder to start, impair it’s power output, and can cause a major degradation in fuel economy, a significant factor in today’s world of three dollar-a-gallon gasoline. “Happily,” adds O’Dowd, changing your car’s air filter is quick, easy, and inexpensive. Older cars most often had an oval-shaped air filter resting in a round housing under a lid held in place by a wing nut. Today’s more sophisticated fuel-injected engines normally make use of a flat, rectangular panel-type air filter that most often lives in black plastic air intact system in the engine compartment. Usually all that’s needed is to release several clamps, separate the housing halves, lift out the old filter, and install the new one. It’s usually that simple, says O’Dowd. As with oil filters, it’s best to choose a name-brand filter whose quality and design features are reliable. After all, says O’Dowd, you’re only changing your air filter once a year, unless you’re driving in unusually dirty or dusty conditions, so it pays to select a filter that will provide reliable and efficient filtering. Fuel Filters Fuel filters are often overlooked during vehicle service because they’re tucked away under the car in many cases, says Purolator’s O’Dowd. But the need for regular replacement is more important than ever thanks to the precision of the fuel injectors used in most of today’s cars, light trucks, and SUVs. Contaminants can easily enter your car’s fuel system through accidental entry during fueling.

How to make fresh cabin air

If you are driving a vehicle with cabin air filters you are in luck, especially if you reside in a metropolitan area where air pollution levels are high or if you suffer from a respiratory condition such as asthma or seasonal allergies.

Cabin air filters capture potentially harmful particulates so they are not recycled into the passenger compartment and compromise the driving comfort of the people in the vehicle.

Normally, motorists roll down their windows to get ‘fresh’ air. Instead, you may want to roll up the windows to prevent the environmental pollutants from entering your vehicle because, whether you turn on the air conditioning or open the fresh air vent, the cabin air filter will provide clean, fresh air while filtering out the environmental pollutants.

According to the Asthma and Allergy Foundation of America ( 60 million Americans (one in every five) suffer from asthma and seasonal allergies and the numbers are increasing. To highlight the problem and related issues with children and adults, May has been declared National Asthma and Allergy Awareness Month.

“For people who suffer from a respiratory-related illnesses or those who are passionate about breathing clean air, cabin air filters are an extremely useful feature on vehicles,” said Kevin O’Dowd, Director of Marketing & Communications at MANN+HUMMEL Purolator Filters NA LLC.

Inventor of the first automotive oil filter in 1923, Purolator offers premium quality BreatheEASY® cabin air filters for most domestic and imported vehicles. Purolator’s BreatheEASY cabin air filters feature a non-woven, engineered media that traps even the finest particles of harmful dust, soot and pollen, adsorbs most toxic odors, and reduces the accumulation of dust inside the car.

A cabin air filter may also be called a pollen filter, air-conditioning filter, passenger compartment air filter, interior ventilation filter or dust filter.

Two kinds of cabin filters are available for modern vehicles – the particulate cabin filter and the activated charcoal cabin filter. The particulate cabin filter features a multi-layer design with pleats that provide more surface area to filter out pollutants. Other features include foam perimeter gaskets and an injection-molded frame when specified by the vehicle manufacturer. The activated charcoal cabin filter goes a step further. It adsorbs most toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons. The additional cover layer makes for extra protection.

Purolator offers both particulate type and activated charcoal type cabin filters for many vehicles, and you can replace a used cabin filter with either type, regardless of which was installed by the vehicle’s manufacturer.

Recent estimates show that since 2001 approximately 45 million vehicles in the U.S. have been factory-equipped with cabin air filters. Refer to your owner’s manual or check with your technician to see if your vehicle has one. The cabin air filter may be located behind the glove box, under the hood near the windshield, or under the dash.

According to O’Dowd, the time it takes to install a cabin air filter professionally or otherwise varies with the make and model of the vehicle. Each Purolator BreatheEASY cabin air filter comes with a vehicle-specific instruction sheet that shows the location of the filter as well as gives step-by-step installation instructions.

How Best To Do It Shield Your Children From Dirty Air While Driving

The Council states, that children, by virtue of their physical size and lifestyle, are more exposed to pollution and also more susceptible to its adverse effects than adults. Whether at school or at home, on the soccer field or at a softball game, children are more likely to be exposed to outdoor pollution. They are also more likely to being driven to these venues in cars, vans or SUVs that potentially only add to their exposure. Particulate and exhaust fumes such as fine dust, diesel soot, pollen bacteria and nitrogen oxides enter the vehicle through the vents and concentrations of these toxic substances inside can be higher than at the side of the road in urban traffic conditions. All this when children’s immune systems are not developed enough to be able to resist and overcome the toxins they encounter.

Plus, because they are young, there is plenty more time for these toxins to get absorbed into their systems and affect children’s growth and development. However, the news is not all bad for parents and guardians who want to shield their young charges from environmental toxins … especially when driving or stuck in traffic even if the vehicle’s windows are rolled up in the car. The Skinny On Air Quality Inside Your Vehicle “The air inside your vehicle can sometimes be even more polluted that the air outside,” said Kevin O’Dowd, spokesman for MANN+HUMMEL Purolator Filters, a leading supplier of automotive filters to the aftermarket in North America. Many motorists are not aware that, for more than a decade, most cars and light trucks (1995 and newer) have been factory-equipped with cabin air filters that are designed to clean the air that you and your passengers breathe. If a filter is clogged it can actually multiply the dangers from particulate matter and other pollutants that get trapped inside a vehicle and blown about when the air conditioning system or heating system is in use Furthermore , the contaminants that build up on a filter over time, become a breeding ground for mold and mildew growth. So, according to O’Dowd, even if you roll up the windows and turn on the air conditioning before you get on the road, the vehicle’s interior is still vulnerable to environmental pollution – if the cabin air filter is not clean. “If you want to actually see the value of cabin air filters, just ask your auto service professional to show you an old, dirty one,” said O’Dowd. “One look at a clogged cabin air filter will convince you that there’s a great deal of dust, dirt, and other contaminants floating around in your car’s cockpit. Breathing that debris can be damaging to your health, especially if you happen to suffer from seasonal allergies or ailments like asthma,” O’Dowd explained. Investing In Your And Your Children’s Health “A good rule of thumb, therefore, is,” as O’Dowd suggested, “to replace the cabin air filter about every 12,000 to 18,000 miles to ensure that you and your family breathe clean, fresh air.”

Purolator offers two types of BreatheEasy® cabin air filters – the standard particulate filter that traps all types of airborne particles including those originating from molds and spores and an upgraded filter that also removes unpleasant odors from the air like pungent, stinking and placid odors. The standard BreatheEasy filter features a non-woven scientifically engineered media formed into a multi-layer design with pleats, which provides more surface area to filter out pollen and particulate matter. These filters are also electrostatically charged to ensure that even the minute particulate matter gets trapped in the filter media similar to many household HVAC filters. Other features include foam perimeter gaskets and an injection-molded frame, when specified by the vehicle manufacturer. The upgraded BreatheEasy filter, on the other hand, features an activated charcoal filter layer that adsorbs most toxic and foul-smelling gases, such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons. Cabin air filters are easy to replace. But, where do you find the cabin air filter in your vehicle? “The cabin air filter is normally located in the cabin air intake, under the dash or sometimes behind the glove box,” said Nuñez. “Replacing the filter generally takes anywhere from 10 minutes to an hour, depending on its location and the design of the vehicle.” BreatheEasy cabin air filters are available for most late-model domestic and import vehicles.

A variety of existing potential problems

“When the check engine light comes on, it means that a vehicle system, such as the ignition, fuel injection or emission control, is not operating properly, even if the vehicle appears to be running normally,” said Rich White, executive director, Car Care Council. “A glowing check engine light doesn’t mean you have to immediately pull the car to the side of the road, but it does mean you should get the car checked out as soon as possible. Ignoring the warning light could result in costly repairs. At the very least, the light could alert you to an engine problem that is negatively impacting fuel economy.”

Some common malfunctions that can cause the check engine light to illuminate include a faulty oxygen sensor, mass air flow sensor, or spark plugs and wires. If the light flashes, the condition is more critical and must be checked immediately to prevent severe damage, which may include catalytic converter damage.

When scheduling service, make sure the automotive shop that examines your vehicle has professional technicians who are trained and certified in OBDII diagnosis and repair. The technician will connect your vehicle’s computer system to a diagnostic scan tool, which will provide trouble codes indicating why the check engine light was activated.

While the diagnostic tool is connected, the technician can analyze data streams such as the idle speed, throttle response, engine temperature, fuel system pressure, manifold vacuum, exhaust emission levels and many other key indicators. Once the problem is fixed, the car’s computer is reset to initiate the computer’s release process. The technician should then advise the customer of the proper course of action, potential warranty coverage, further testing if necessary and recommended repairs.

Getting an oil change on your car

However, all oil changes are not alike. And whether you do it yourself or have it done for you by a professional, the same rules will apply.

So how can you make sure that your vehicle gets the best possible oil change? Simply follow the tips outlined below.

1. Allow your vehicle’s engine to warm up fully. Once an engine is warmed up completely, all the dirt particles and contaminants that settled at the bottom of the oil pan when the engine was off get churned up and suspended in the oil. This will ensure that most of the contaminants get removed when the oil is drained. In other words, they will be drained out with the old oil.

2. Make sure the vehicle is level when the oil is being drained. This enables the old, dirty oil to drain out as completely as possible.

3. Examine the waste oil as it is draining into the pan – look and feel. Look for signs of contamination such as water because with every drain, water will settle at the bottom of the pan. Also, feel for bits of metal which could suggest internal engine problems. You may not have noticed the last time you took your car in for an oil change but a good mechanic normally will run his fingers through the oil while it is draining to ‘feel’ for grit, metal and other contaminants that signal possible engine problems.

4. Remove and inspect the old filter carefully. Most modern cars use a spin-on oil filter. Spin-on oil filters were invented in 1955 by Purolator, today, the supplier of high quality oil, air, cabin air, fuel and transmission filters as well as PCV valves and breathers to the North American aftermarket and car manufacturers. Most important, when removing the filter, make sure that the gasket sealing ring comes off with the filter. If it does not, use your fingernail to pry it loose and remove it.

5. Now choose your new filter carefully. Select one that has been manufactured by a company widely known for the quality and efficiency of its filtration products like Purolator for example. Purolator has been in the business for the last 90 years since it introduced the first automotive filter in 1923.

“The performance of a filter is determined by its efficiency in capturing contaminants and its capacity to hold that debris,” said Kevin O’Dowd, spokesman for MANN+HUMMEL Purolator Filters. Purolator’s premium grade PureONE oil filter, for example, is 99.9 percent efficient and can hold up to 13 grams of debris, the equivalent of 31 standard size paper clips. Purolator Classic oil filter, on the other hand, according to O’Dowd, features a multi-fiber high-density media that holds back engine-damaging dirt and pollutants and is 97.5 percent efficient in capturing contaminants. Where applicable, both filters also feature an anti-drainback valve that protects against engine dry stars.

6. Install the filter properly. Make sure to coat the sealing ring with fresh motor oil and install it hand tight only. Purolator PureONE’s unique 100 percent grip control feature keeps fingers from slipping and makes installation trouble-free at any angle. Additionally, its PTFE-treated sealing gasket makes removal and installation easy and problem-free. Purolator Classic features an internally lubricated Nitrile gasket that makes filter removal easier.

7. Choose the correct grade of new oil. Oil is the lifeblood of the engine and choosing the appropriate grade will ensure proper performance. Refer to your owner’s manual for the correct service designation. It will be specified as an API (American Petroleum Institute) rating. If you happen to be working on a vehicle with a diesel engine, then remember it requires oil that is specifically formulated for diesel service and has a separate API rating. While there are pros and cons to using synthetic oil versus conventional oil, you can’t go wrong if you follow the recommendations in your owner’s manual.

Change Your Driving Style

changing your driving habits to suit a car that performs better will use less fuel and protect your wallet at the pump. Clean air = long life and improved performance “The logic is the same,” O’Dowd says. “Just as breathing clean air contributes to a long and healthy life, so also a vehicle’s engine that ‘breathes’ clean air performs better over a longer period of time. Abrasive dust, dirt and other contaminants that can enter through the engine’s air intake ducts while you are driving can damage a car’s internal engine components, increase wear and ultimately reduce the engine’s power, performance and long life. A vehicle ingests about 10,000 gallons of air to burn a single gallon of fuel and, air along roads and highways contains all kinds of contaminants such as soot, dirt, leaves, straw, tiny bits of rubber, etc. Large quantities of unfiltered air entering the engine compartment can damage critical engine components and cause cylinder wear. Choosing a quality air filter “Capacity and efficiency in capturing the dirt before it enters the engine combustion chamber are key to determining the quality of an air filter,” says O’Dowd. “Capacity is the amount of dirt the filter can hold before it begins to restrict air flow and efficiency describes how well it performs in capturing the dirt.” Modern engines that are built to be more fuel-efficient and have smaller openings and tighter tolerances call for engine air filters that can trap even the smallest particle of dirt threatening to enter the system. For instance, Purolator’s PureONE air filter’s oil-wetted, high-capacity media offers twice the capacity of conventional filters to trap contaminants smaller than the size of a grain of sand and is 99.5 percent efficient over a range of 1-200 microns using A4 coarse test dust. This means it traps 99.5 percent of particles that size or larger.


Likewise, Purolator’s Classic air filter multi-fiber, high-density media traps 96.5 percent of contaminants. Most people should change their vehicle’s engine air filter once a year or every 12,000 miles unless they’re driving in unusually dirty or dusty conditions, suggests O’Dowd. Because of the long intervals between changes it’s important to install the best filter possible for reliable and efficient filtering. Drive to save So, what kind of adjustments will you need to make in how you drive to take full advantage of that improvement? · Avoid making “jackrabbit” starts and stops. You need apply a lot less pressure on the gas pedal or the brakes if you give yourself enough time to get to your destination. · Drive gently and smoothly for a more comfortable ride. Aggressive and fast driving will waste gas and lower gas mileage by 33 percent on the highway and by 5 percent around town, according to the EPA. · Stay within speed limits. Gas mileage decreases rapidly at speeds above 60 mph. Each additional 5 mph increases fuel usage by about 7-8 percent (calculation based on EPA figures – see Web site mentioned above). In the final analysis It’s always best to opt for a name-brand filter whose quality and design features are reliable and well documented, says O’Dowd. “Experience and documented innovation are key considerations with a product like an engine air filter that can have a major influence on the life of a $4,000 automobile engine. Think about it, if you need surgery, you will certainly want an experienced surgeon who has performed many operations and who has a track record of successful outcomes.”

Readings and negatively affect the air to fuel ratio

Signs of a dirty MAF sensor could be a check engine light.  You may experience a loss of power, stalling, rough idle.  Your engine may also be running rich and producing excess emissions.  The original Mass Air Flow Sensor Cleaner from CRC Industries is a unique precision cleaner specifically developed to clean sensitive components in MAF sensors without damaging or degrading plastic or painted surfaces.

Use CRC Mass Air Flow Sensor Cleaner with the engine off. Always wear gloves and eye protection, and insert the straw into the nozzle before an application.  Remove the air filter to gain access to the MAF sensor located between the air box and the throttle body.  It is recommended that you remove the sensor for best cleaning, but it’s not absolutely necessary.  Place a towel under the MAF to catch any run-off.  Using the straw attachment, apply 10 to 15 short bursts of CRC Mass Air Flow Sensor Cleaner to the hotwire or the hot plate.  Be careful not to let the straw, or anything else come in contact with hotwire. Keep the end of the straw 4 to 5 inches from the hotwire.  Be sure to spray all sides of the MAF sensor and clean all wires and connectors.  Reassemble the MAF and allow to dry thoroughly before restarting the engine.

Often, technicians will try to use throttle body, carburetor, or brake parts cleaners to clean sensitive MAF sensor components.  However, these aggressive cleaners can be damaging to plastic, which most MAF sensors are housed in today.  If the plastic degrades or warps, the MAF hotwire can shift and malfunction, resulting in expensive repairs.  Use only the original Mass Air Flow Sensor Cleaner from CRC Industries to safely clean the delicate components of the sensor.  Regular use will restore horsepower, reduce rough idle, decrease hesitation and pinging and improve gas mileage.

A fact that deposits form in every fuel system

GDI engines are particularly prone to rapid build-up of fuel deposits because they’re never cooled or washed with fuel.  Deposits can form in as few as 5,000 to 10,000 miles, restricting proper airflow and increasing engine operating temperatures.  These harmful fuel deposits cause a variety of problems, preventing your vehicle from operating properly.  Unlike common fuel additives that are diluted into fuel before reaching critical fuel system components, GDI IVD Intake Valve Cleaner from CRC Industries is sprayed directly into the air intake system.  This powerful cleaner hits the back of the intake valves at 150 times the concentration of premium fuel additives.  Intake Valve Cleaner is proven to remove up to 23% of carbon build-up in the first hour of use.  It works in all gas-powered engines, not just GDI.  When using Intake Valve Cleaner from CRC, time consuming and costly engine teardown is no longer required to clean intake valves, especially on GDI engines where previously, engine teardown was the only option.

Apply GDI IVD Intake Valve Cleaner with the engine running and at operating temperature.  The unique PermaStraw actuator locks into place, preventing the straw from being drawn into the air intake.  Remove the air filter cover and locate the MAF sensor between the air box and throttle body.  Have someone rev the engine to about 2000 rpms and, engage or lift the PermaStraw Dual-Action Spray System and insert past the MAF sensor.  It’s very important that you do not spray the product in front of the MAF sensor. This could cause the system to throw a code.

You may need to disassemble the air intake to spray the product past the MAF sensor. Again, with the engine running at 2000 rpms, spray the product into the air intake behind the MAF sensor, spraying continuously in 30-second intervals until the can is empty.  If necessary, accelerate slightly during the application to avoid stalling but don’t exceed 3500 rpms.  When the can is empty, accelerate the engine 2 to 3 times but no higher than 3500 rpms.  Run at idle for one minute and, then turn the engine off.

After application, reassemble the air intake system and let the engine “heat-soak” for an hour.  Restart the engine and drive at highway speeds for about 10 minutes.  Using CRC Intake Valve Cleaner will increase power and torque.  It stabilizes rough idle and solves rough starting problems.  It is highly effective for all gasoline engines and regular use will reduce emissions and improve fuel economy.
