Car: The fiance's '00 Alero 2.4L (68k miles).

Problem: Fast idle
Conditions: Cold start, hot start, any time.
Problem: When Cold - Engine rev's upto ~4k rpm upon startup and hangs there a few secs (2-3). Then slowly drops to ~1.5-1.8k idle. When hot - Engine rev's to ~2.5k and idles ~1.2-1.5k rpm.
What we've done so far: Check plugs & wires, Replaced downstream O2 sensor (had a CEL for it), replaced fuel filter, checked and replaced IAC valve, replaced TPS sensor (had a CEL for it), had an independant shop look at it and say "We dont know".
Need to fix by: December - for NYS Inspection reasons.

Don't want to take it to a GM dealership and pay $90/hr unless we have to.

Only other idea I have is a reflash of the BCM/ECM :crap:

Thanks..
