He's right. I had the same problem about a week ago. Taasman dropped me a PM to try cleaning the IAC. I did it and the car started. It has been running normal since. Just for the heck of it, I also cleaned the TB. If your rpms have been very jumpy in idle, especially upon cranking the car, it might be a good idea to try cleaning it. I thought the idle was jumpy due to the cold, however since cleaning the IAC, the idle has been normal upon cranking. Give it a try.
