I have "heard" but don't hold me to this, if you start the car and unplug IAC while it is running then shut the car off for a few and restart with it unplugged it will bypass it, if this is true and it idles normal after then that will tell you IAC problem but that procedure don't make sense to me but it worth a shot. It's gotta be the MAF or IAC though.
