I removed the IAC and watched it move up and down, seems ok. I even replaced it with a unit from AutoZone and it made no difference. I can unplug the IAC and there is no affect. I coonect a tester to the IAC and was able to open it and close it. If I squeeze the hose that goes to the IAC value I can bring the idle back to normal. I don't hear any other vaccum leaks. I'm wondering if I should have cleared the PCM when I tried the new IAC value from Autozone, I didn't do this step. Any ideas.
have the same problem?
