I was driving with some buddies the other day, and we pulled up to a stoplight and the car died. I had been noticing a somewhat crappy idle when the car was cold for the past few days, but it was always smooth and fine when it was warmed up. But when this happened, the car was fully warmed up so i don't know whats going on. I was able to get the car started back up and i made it all the way home just fine. As soon as i pulled into the driveway however, the car died. It just wont idle. I can start it for a second, but it just dies. I can keep it running if i rev it, but it just won't idle. Anybody have this problem or know what is happening? I'll try to get a video up here later.

Car is in Sig

 

try cleaning the Iac (idle air control) sensor on the throttle body and see if it helps. and clean the throttle body too while your at it.
