2002 Ford Focus ZX3 problems

My Focus ZX3 has 28,000 miles and so far, I have had an oil gasket leak repaired (under warranty), and rotors replaced because they were "prematurely worn" (under warranty). Now the car sort of "vibrates" (slightly, but I can feel the difference), and feels like it slightly "putts." Has anyone had similar problems/situations?

is the vibrating coming from the engine? or its just vibrating from something else

is the vibrating coming from the engine? or its just vibrating from something else

I wouldn't know how to answer that. It just doesn't seem as "tight" as before and what concerns me more is the slight "putting" I feel. Imagine when an engine backfires and the car suddenly stalls for an instant before moving on, well, in this case, it's not dramatic like that, but very distantly like that, if that makes any sense?

Without any more details, the only thing that comes to mind are some bad motor mounts that are transferring too much vibrations...you may want to run a diagnostic scan to make sure that the computer isn't reading any codes that might make the motor run poorly.

well...what do you mean by it doesnt feel as tight as it was before...do you mean that it doesnt have the old quick responsivness or you have to rev it up more than usual to get it going b/c there might be something going on with your transmission...and i would check the codes also like he suggested
