I have a question since ford cant find the problem. I have a 05 st with 32000 miles. Well when i put it in reverse or drive it has a vibration real bad but only once in a while. It started doing it just the other day so i drove straight to ford and they looked at it for a couple of days and said it was fine. Do you guys have the same problem or should i take it back to them and tell them to do more research or am i just being to picky about how the car runs. Oh and by the way i have no mods done to the car.
