Your Idle Air Control (IAC) valve may be dirty with carbon, simple fix with throttle body cleaner through the IAC passageway through the throttle body. Make sure it's throttle body cleaner and not carburetor cleaner, the carb cleaner is to corrosive to the gaskets used on the throttle body.
If cleaning the IAC does not help, then it's a good chance that the IAC is to far gone and will need to be replaced.
Good luck and thank you for using fixya

2002 auto saturn sl1 revs a little high, and shifts a little hard when going between gears?


I just went through the same thing and checked the air idle control valve, and the throttle position sensor. . took it off and cleaned it. I took off the throttle body and cleaned it. Listened for vacuum leaks. Then after the same problem persisted, I sprayed brake cleaner directly on the intake manifold gasket between cylinders 1 and 2 and just like that, the RPM"S went down. I need a new intake manifold gasket.

Chevy 2002 Malibu ERG valve


Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.
