Sorry to bump this up, I've been having the same high idle issues for a while now. It starts up when when the car is usually completely warmed up and only in stop-and-go traffic type situations, it usually likes to stay at around 1750 rpm and stays there. I cleaned the MAF sensor with CRC sensor cleaner and some q-tips, cleaned the IACV and replaced the gasket, neither of these seemed to work. I took it down to independent automotive and they couldn't replicate the issue. About how much slack should be in the throttle cable? I can push it down a little bit with my finger but it's not super loose or anything. Same with the cruise control cable.... What am I missing?
