I have a fast idle, about 2k to 2.2k, at startup whether hot or cold, every time. If cold, idle will come down to1500 in about 5 seconds, then within a couple of minutes it will come down to normal IF I roll to a STOP. Thereafter it idles normally. If hot, engine will come down to a normal idle after a minute or two, IF I roll to a STOP, otherwise stays up until I come to a stop. After that, behaves normally. No CEL and no codes in the PCM
I have done the routine. I cleaned the IAC, cleaned the MAF, checked the throttle body, seamed reasonably clean, replaced air filter, disconnected battery for 15 min, checked electrical connections, etc. I have also disconnected the IAC, and the engine barely or won't idle, which indicates no leakage of air around the throttle plate and probably no vacuum leaks.
Some folks have said engine should idle fast at startup, but this is way too high and a bother.
Vehicle is a 2004 with 105, 000 miles and is in good condition. I have only had it for a few weeks. It is a 4.0 with manual.
When I come up with a problem, and gotta ask for help, it ain't simple!
