I think I found my vibration problem

So your trying to say you adjusted the pinion angle and that fixed your vibration that was there when the car wasn't moving?

didn't say that. you did. I said with the car sitting still I had a quiver in the engine when I brought the RPM up to about 1500. The engine still has a harmonic imbalance but the vibration when driving is all but gone.
