If you’ve installed a cold air intake system on your car, you were expecting performance gains not headache pain! Your engine may have overheated or your check engine light may have come on…all because you installed a cold air intake kit!
Before we look at how to diagnose problems you may be experiencing with your cold air intake system, lets take a quick look at the basics.
What Is A Cold Air Intake System?
A cold air intake system is an aftermarket product used to bring cool or cold outside air into your car’s engine. Because cold air is denser, it allows the air to flow better through the engine and helps increase horsepower and, in some instances, fuel economy. Quick and inexpensive horsepower gains has made the cold air intake one of the most popular products for increasing engine performance and efficiency.
How Can You Quickly Troubleshoot Cold Air Intake Problems?
- As with many car upgrade or repair procedures, make sure you disconnect the battery before starting. This will help eliminate trouble codes being displayed.
- Check for whining noises. If you hear whining noises, this normally indicates that a vacuum hose is loose. Tighten the hose clamp to prevent any leaks. This will eliminate any excessive noise or whining sounds coming from the engine. Rev the engine and have someone listen to the engine while you are testing the car.
- Check the air filter to make sure it is clean and free of dirt and debris.
- If you get a check engine light error, reset the ECU (engine control unit) by unplugging the battery. Because a cold air intake allows cooler air from the outside to enter into your engine, it may throw the sensor off causing the check engine light to come on. The amount of air now coming into the engine is most likely greater than what the ECU expects, therefore triggering the check engine light. This will eventually take care of itself because the ECU will adjust to it.
- You may also receive a code for lean gas with the check engine light. This simply means that more oxygen is entering the cylinder and producing a more powerful combustion. Simply resetting the mass air flow sensor can resolve this issue.
- Make sure you install a cold air intake kit that comes with an oxygen sensor. You can find several to choose from at AutoAnything.com. Their cold air intake kits are easy to install, affordable, and are available from several high quality manufacturers.
