did you do any recent work on it? if the shake is always there check the driveshaft. is the car shaking or is the motor shaking the car, might be missing. something to look at

I was going to say check you plug wires, mine was missing and studdering when acelerating, if that doesnt help chances are its the plugs.

The plugs are probaly the problem, injector flush? never heard of that, nothing alittle sea foam or injector cleaner cant fix.

Plugs are good, and injector cleaner didnt do it.
when it gets shaky like that the needle on the tac skips when it hits about 2500 -3500 rpm

Plug wires maybe, my spark plugs looked good too but really from the car sitting really took its toll.

There would be a lot I would check before I would assume the injectors are bad. First check fuel pressure and the resistance across each fuel injector. Does the car shake at idle, or only over a certain RPM? Also, what kind of exhaust work? If it was up by the engine they may have routed your wires poorly causing one to sit on your manifolds and burn through. Injectors may be your problem, but would not be my first suspect.
