Air Idle Control Motor (ICM) regulates the air at idle through the throttle body. The car's computer controls the amount of air going into the engine by controlling the ICM.  These replace the function of the idle speed screw used on the older carburetors which held the air plates (or butterfly valve) open a small amount. Common problems for the air valves are deposits that cause the valve to stick or become plugged. Symptoms of a defective or plugged unit can include rough idle, or a car that wants to die at idle, but runs well above at normal driving speeds. The Idle Speed Motor works similar to the Air Idle Control motor.

This 85-92 Idle Control Motor (ICM) is for your Camaro, Iroc, Z28, RS, Firebird, Trans Am, Formula or GTA
