I haven't had a single problem with the idle if you want to try the IAC thing....i drove it until it was nice and hot, then i idled it for a while...it was at a steady 900 and never faultered...
i mean it can't hurt to try this:
with the key off, slightly depress the gas, then start the car, take you foot off the gas once it's started.
let the engine idle for 5 seconds, then turn off the car for 10 seconds.
start the car again and drive as normal...
give it a shot, hell it doesn't cost a thing and who knows, it may work
