car vibrates (the girls enjoy taking rides with me)

*OK NOW THAT I GOT YOUR ATTENTION*
OK i got a problem with my gst, if i push the gas a 1/4 throttle the car drives fine, then if i give it right to the floor the car vibrates to the point were your hands are numb by the time you arrive at you destination. if you dont push the gas all the way it wont do it. if you floor it in like any gear it will vibrate. I pushed the clutch in and gave it gas up to at least 5k and it didnt sound like the motor was studdering at all or anything, so im guessing its in the drive train. also if i gradually pick up speed the car will start to do the vibrating at 50mph.

i really need help guys i have no clue what the hell it is.

Alright first check to see if the tires are balanced

Also My cars doing the same thing now....My old axles are on their way out and with my recent lower the axles make my car shake like no other.

Its only with anything above alittle throttle and its gets alot worse up hills. is your car lowerd and has it done this since you have gotten it ? How many miles?

Also rule out the dumb stuff first like lug nuts being tight or bent rims. good luck

i just put 10 more miles on it and i dont dare to drive it anymore, the car i just bought so dont remeber the milage ill check and let you know later, no its not lowerd. hills are scary as hell.

Also it wont do it at slower speeds, well not as noticeable, when it does it, it feels like spark plugs and wires are bad, but there not.

Yea that exactly how mine is. I think it could be your axles.....check all the other stuff first but im betting on the axles. If your going and let off the gas does it sort of go away when you coast, but then when you hit the gas again it just picks right back up ?

Its your dam engine mounts i have same problem i just noticed my front and rear mounts are snapped and side one is almost gone. Time for prothane mounts

Well here is what i came up with, the car vibration goes away when let off the gas.


the engine mounts the little rubber things on the end. i can spin those all the way around by hand! is this normal?

Look in to both, but mine does the same thing as yours, and Im sure my axles are the problem good luck.
