I just purchased a car with a 2.0 Zetec with the same Bucking problem. My problem happens mostly under 3500 RPM with light throttle, usually when letting off the gas. Did anyone ever solve your problem permanently? I read the post in this thread about changing the plugs being the fix, but I am wondering if anyone has had sucesss with this or other solutions? If so what did you do??
thanks very much Jeff A., West of Boston
