My 97, 125K has an intermittent high idle, usually in the morning after I exit the highway going to work. I have shut off the engine in the parking lot, restart and things went back to normal.
This morning, happened again and disconnected IAC valve wire and idle returned to normal. Plug it back in, high idle.
I bought a new IAC today ($40), but still want to be certain that's the culprit. In another thread, soemone mentioned that this condition sounds like cold-high idle, maybe the temp switch being bad.
Otherwise the engine runs and idles well. Cleaned the IAC a few weeks back, but it didn't look dirty.
