Hi chainman,

The purpose of the IAC is to control the idling speed. If there are any changes in engine electrical load, the engine rpm would drop and the IAC would be informed by the PCM to open up to allow more air into the intake which would increase the idling speed.

What you are experiencing could be a dirty IAC and throttle body. Get them cleaned and see if problem goes away.
