fast idle
I have a 325 is 1987. when the a/c is on and the car warms up the revs go up to 21-2500, it remain there for a while and then it drops down to 900, and it goes back to the same cycle. It only happens when the a/c is on.
Changed the idle valve. Still same problem. Help!!!!!!!!!!!!!!!!!!! what else could it be short of experimenting $$$$$ with something else
