You're saying that at a stop, if you rev the engine up to 3,000 it will vibrate? That would isolate the problem to the engine and attached pieces. Vibration damper could have slipped or the flywheel could have come loose. Valve adjustment is off or a valve is bent. The list goes on and on. Vacuum leak or cracked distributor cap is mis-firing.
