There is an air control valve located on the 2001 Saturn SL1

There is a four-word car part.I promise, you can keep up.The engine idling speed is controlled by an iac valve.See?Told you it was easy.The engine control module supplies voltage to the IAC valve, which in turn causes a pintle or rotary valve to move in and out of the car.A higher idle is a result of more air.Most modern cars have electronic throttle bodies, so your car might not have an IAC valve.You can skip this information if your car doesn't have an IAC valve.It will not need an IAC valve replacement if it does not have one.

Are you ready for some news that will knock your socks off?The idling might not work right if the IAC valve isn't working.If you feel like your car is idling too high or too low, there is a good chance your IAC valve is the culprit.

I understand.You might not notice when the speed is off.That is understandable.When the engine isn't performing well, you better notice.There is a sign of an IAC valve that is not up to the task.In more extreme cases, a car that won't turn on is also stalling.

Did you not want to see this listed as a symptom?I understand.The check engine light is not something you pay attention to.It is small and harmless looking, so you think it is meaningless.It is not meaningless.It is possible that the IAC valve is the problem with your car.

It is not good to ignore a malfunctioning IAC valve.You might get stuck with a car that won't turn on, or will stall at a red light, because your car will not perform well.Not good.If you drive around with a busted IAC valve, you won't put your engine at risk of further damage.
