i have a 2000 gt, just bought it..brand new to fords in general. my problem is.... the guy i bought it from had a clutch installed he said about 200 miles ago, ...note that the car is on sr lowering springs also....anyway when i start off in 1st to take off at a normal acceleration the car vibrates and shakes sort of like its going to stall, but also feels like wheel hop. i am not sure what is going on and i really need to get this taken care of!...also when i first start the car it goes smooth the first two or three times i take off. after that...horrible vibration/shudder. any help would be appreciated...thanks!
