Vibration / Shaking From Egine

[dineth]

Hey guys! need some advice / help! got my car serviced recently and ever since then the car has been running pretty crappy! I cant figure out what it is, it runs fine mostly, but when i let go of the throttle i can feel a vibration coming through the car, can feel it through the drivers seat and through the foot rest where the clutch would be (cars auto), that whole left side vibrates, not dramatically, but enough to notice easily. It seems to get worse on lower revs and i can't figure out what it is, coil packs and plugs are fine, car was running fine before the service. The car doesn't sound the same as it used to either, seems to be more quieter than normal on idle and as i said when i rev upto like 2K and then slowly let og of the throttle i can feel the car vibrate and then become stable again, really weird! HELP!

car: R33 Gts-t Auto

mods: turbo back exhuast, Pod, R34 Side mount, bleed valve boosted to around 9-10psi and SAFCII tuned by RE customs

what the service guys did:

change plugs

change belts (not the timing though)

oil change

auto transmission fluid change

thanks!

A) You're posting on the NA forums.

B) Maybe they put the wrong tranny fluid in?

Possible engine or gearbox mounts need replacing?

take it back to the mechanic that done the service for you, tell him you are not happy as the car is vibrating now.
