adjusting idle speed?

Recommended Posts

Unplug the idle air controller, then adjust the air screw (on the throttle body next to the IAC) until it idles around 500 rpm. Plug the IAC back in and go.

 

Actually, your IAC may not be functioning. Does the engine idle faster when it's cold, or does it always idle at the same speed? If the speed does not fluctuate, the IAC may be faulty or gummed up.
