So I have an 02 mustang gt. There was a problem where the car kept idling bad then stalling out always upon stopping, mechanic shop changed IAC 4 times and the said the fourth one was the charm. Sounded strange to me. But I got the car back and everything runs fine
Except for everyone once in the most random while, the car will just die for no reason when slowing down. I'll just start it back up and keep driving. Any ideas why?
