NOTE: THESE HAVE BEEN DISCONTINUED.. if you need one .. don't sit around thinking about it.. its common for parts like this to be sold off back to the USA.. and they already cost more then this even on places like ebay.

This is the original Cross Fire Injected - Idle Air Control Valve.. one used on each of the carbies... these are GM new parts..

• FUNCTION: The 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 unit or defective plug ON the unit - can include rough idle, or a car that wants to cut off at idle, but runs well above at normal driving speeds.
