I am having a vibration problem,its there when i start the car and its apparent at highway speeds.The vbration is not in the drivetrain(trans,driveline,rearend) due to isolateing it at a stop with the trans in gear and the clutch in.the engine run perfect ,it is not a miss ,or a dead cylinder.Has anyone ever had this kind of a problem.the car is a 95 gt 5.0 with a 5spd,i am baffled. thanks Todd Wilson
