I had been having some troubles with the idle speed going high after it warmed, up, around 1200-1300 rpm, but not always.

It would start normally, run at regular idle and then sometimes runup in idle. If I shut the car down and restarted it, it cleared sometimes. It usually took many cranks to get it going. .....

Since then I have done some tests on the IAC and put an O-scope on the signal. I took it appart and cleaned it, everything looked good. It pretty much stays open all the time, but perhaps someone on can tell me if what I see as diagnostics makes sense.

I have an image at http://home.comcast.net/~jaznm/ that shows what I have found.
