I'd try cleaning your MAF, and if you can, get a reading on your vacuum. I would almost bet it on being your MAF... it might be just dirty, or the heating wire on it is faulty.

If turning the AC on fixes it, wouldn't it have something to do with idle speed adjustment ... idle air control valve maybe? Wouldn't that also be consistent with cold idle fine, hot idle bad?
