When it gets much above 80-85F, the air intake starts humming, and can get quite loud. The engine still runs fine, but the noise is annoyingly loud. Its loudest when idling. It comes out of the air intake system, and I think its associated with the IAC valve or the IAT sensor possibly. Any ideas? Is this common?
Thanks

You are right, it is the IAC, and the way to fix it is unfortunately, buy a new one, and they are about fifty dollars at auto zone.
