Re: Idle RPM not consistent
Still sounds like the IAC to me. If the TB was pretty gummed up, my bet is so is the IAC valve. I'd pull it off and clean it really good with some TB safe cleaner and a brass wire brush (that's how I clean mine without damaging anything). Oh yeah, remove the battery cable before you start. That will force the computer to re-learn it's idle and drive settings. It couldn't hurt.
