Gas pedal stuck under carpet.
I own a 2003 Mustang gt 5-speed. It has died numerous times and after the first time I called the Ford consumer hotline and was brushed off. But they did refer me to a local dealer, the same dealer that less than 10mins after the first failure took my car for a short spin and said that my car was a little low on gas and that was the likely cause. I was driving approx. 35mph and was not on the clutch or accelerating. It just died. This is an extremely dangerous problem and needs to be acknowledged. I finally had a dealer diagnose the problem and they replaced my cars iac valve. My car has still died several times but now its when coming to a stop and its been isolated. I feel that a TSB or recall on this long overdue.
