No summary listed for above vehicle.
The docks in this engine set up a harmonic vibration between 1800-2300rpm. Ford has determined this is a normal condition for "some" of these engines. To the unsuspecting buyer of this automobile he/she will have to endure a melodic, approx every second, vibration that is transmitted through the car. From what I have read on various bulletin boards this problem was brought to Ford's attention prior to my purchase but they still continue to produce the automobile and now have concluded this is normal. Please look into this for those of us who have been taken advantage off. Sincerely, bill chase.
