Rough idle cold?

Hey guys, I have a rough idle when I first start the car. Once it warms up the rough idle ( goes away ). And it is not consistent, just a dead miss once in a while. It is still there when it warms up but it is diminshed quite a bit. On warm restarts it is not noticeable either.

Any ideas? Could the IAT be the culprit?

IAC probably causing the trouble but the dead miss is what I would chase first, might have a bad injector or vacuum leak also.
Have you ran any good injecter cleaner thru it yet?

Looks like the IAC is a popular one. I'll have to check that out.

Have not run any injector cleaner thru it. They are the original injectors with 94k on them.

That may help a bit, cleaning the injectors, but the iac should fix your problem completely.
