If you have a 4-cyl then the vibration is pretty much inherent with the Zetec. Not much one can do about it. Mobil 1 and some good plugs can help, but it'll still be noticable.

Of course, "bad" here is kind of subjective. It could be, actually, really bad and fixable. But some heavier-than-normal vibration is the norm with a Zetec 'Tour.
