...as i lift my foot it goes? it can freewheel at any speed without vibrations, its only while accelerating, its not the wheels or mounts, is it the gears, of cv joints, all help appreciated.
I had a new Ford and it was firing on 3 cylinders (it had 4) and been to the Ford garage twice and they did not spot it. Only did when I insisted it was not right and had it checked again.
