Does it do it at every gear? Could be your driveshaft ujoints are bad.

yes everygear

Check driveshaft ujoint jack up car and wiggle the driveshaft where it meets up with the yoke. .

ya i did that and its all fine

Sounds like its starving for fuel...

Check your timing, check the injectors, check cap n rotor, check plugs n wires...

Run some fuel injector cleaner...

It may be a good idea to just replace the plugs cap and rotor all together...

Loose or really worn out motor mounts?

Start with something simply, check your alignment and the balancing of your tires. Our 90 GT would vibrate like that, and found out the tires weren't balanced correctly.
