Well, this problem is turning out to be a real headache! On a cold start, all acts well. The engine idles down to about 650rpm and hangs out there nice and smooth. But, as soon as things get warm under the hood (not closed loop, just warm) and i blip the throttle (and this is necessary to cause the problem, until I touch the gas, all is well), the car settles back down to idle then idles like it is missing like crazy. As soon as I give it some gas, it seems to even out fairly well, though is still a little rough. It is very unhappy settling back to the rough idle. Checked Vac hoses/IAC/ECT. Also, the engine seems to not notice if I disconnect the IAC while its running rough, like its not doing anything.

Help!
