Well after 2 months of putting a new IAC its says my IAC is bad. Code was cleared and then came back. When I start the car for the first time each day the RPMs go to 3000 I have to put it in gear just to drop the RPMS. I looked at the IAC when it was idling and it was moving when I pushed on the butterfly spring. Also the gasket that goes on top of the throttle body has some chunks missing. Called gm and they don't even carry it. I am wondering if that is causing a vacuum leak. This thing is driving me nuts. HELP!
have the same problem?
