Your engine revs when you dont hit the gas?

If your car's engine is revving when you're not pressing the gas pedal, it could be a sign of a problem with the idle control system. The idle control system regulates the amount of air that enters the engine when it is not under load, and it helps to keep the engine running at a steady speed.

There are a few different things that could cause the idle control system to malfunction, including:

* A faulty idle air control valve

* A vacuum leak

* A problem with the throttle position sensor

* A problem with the electronic control unit (ECU)

If you're experiencing this problem, it's important to have your car checked out by a qualified mechanic as soon as possible. Driving with a faulty idle control system can damage your engine.

Here are some additional symptoms that could indicate a problem with the idle control system:

* The engine stalls when you come to a stop

* The engine idles rough or unevenly

* The engine idles at a higher or lower speed than normal

* The engine hesitates or stalls when you accelerate from a stop

If you're experiencing any of these symptoms, it's best to have your car checked out by a mechanic right away.
