Ok this morning on my way to work the car ran fine on the freeway but I pulled into McDonald's for breakfast and sittin in the drive through the car idled rough and when I put it in neutral it died. It restarted but I had to give it a little gas. I'm thinking it's the IAC but before I go to parts and have one taken out of my next check I'd like second opinions from experieced SC people ;). (the two techs I trust with my car here don't work saturdays :()

Check it for vacuum leaks before you spend cash on an IAC. Be sure to check all of the lines for the PCV system on both sides of the engine and intake tube. Good luck
 
Well I took off my tie rolled up my sleeves and popped the hood on my lunch... one of the techs turned it over for me and kept it revvin'... Heard a nice whistle from the IC... further investigation found the nut had come loose and the gasket "blew out" a bit and it was suckin' in all kinds of air.
