I've just had my engine mounts replaced with all new ones and the car is vibrating badly. It is horrible! Have they put the wrong mounts in or what could be the issue? Pls help!

 

My Mazda 626 2.0l vibrated badly and among several fixes I replaced all five motor mounts, but the vibration persisted. Before, I couldn't hear the large vacum leak, but I also replaced both belts and it now runs very quiet. This is when I was able to hear the leak. A couple of days ago I replaced the intake manifold gasket and it now runs so smoothly with no vibration.

 

Vibrations can be caused by many problems. under what conditions is it vibrating? idle? if driving, at what speed? what conditions? decelerating, accelerating? turning? braking? up/downhill while turning/braking?

do these vibrations happen while braking, and feel the vibrations in the steering wheel?

where do you feel the vibrations? in the steering wheel? seat? door? floor? center console?

what other conditions are know good? any misfires? any check engine lights?

 

Problem SOLVED. THEY SOLD ME A DODGY TOP ENGINE MOUNT! REPLACED IT AND RUNNING PERFECT .. PHEW! GOT OUT OF THAT CHEAP (TOUCH WOOD).
