I'm guessing this is your problem. please see attached video:

I’ve already cleaned the IAC valve and the throttle body, neither of which seemed to do anything about the problem, and the codes were not there until the engine died on me. The main thing that is putting me off is that it only every has problems when it’s cold outside (<50F), and runs perfectly normal when it’s warm. I’m going to check on and clean out all the electrical contacts to and from the ECU when I get home from work tonight.
