Thanks Ranger, I was hoping you would chime in. From reading other posts you seem to know your stuff. OK enough brown nosing. I pulled the IAC and it was pretty dirty. One question - should the plunger apparatus move freely? I pushed it in and pulled it out - which took a surprising amount of effort.

OK I cleaned the IAC and reinstalled it. I started the car and let it idle. After the engine warmed up it killed. But, whereas yesterday after it stalled and I restarted the car it would stall again almost immediately, after cleaning the IAC the car would idle for 10-30 secs before stalling again. So, possibly the IAC needs to be replaced?

Another note - when reinstalling the IAC I depresed the plunger fully so it wouldn't be in the way. When I started the car it jumped to 2k rpm and took a good 7 - 8 secs to drop down to 1k rpm. Should the valve be moving that slowly? As stated above it was extremely hard to move the plunger by hand.

I'm thinking we are on the right track here. If I give it even the slightest bit of throttle no problems at all.
