Under load shakes.

I thought injector problem from the first post, now I don't know what the fuck it could be since you said you can move the shifter and it goes away. At higher RPMS you'll feel less shaking with almost any problem. Judging from your post that you beat a 2V 4.6, there can't be too many mods to the car. I'm really thrown for a loop to be honest.

I still wanna say injector since it "goes away" at high RPM's. That's typically the sign of a misfire. Somebody said a "coil"...do you have a modular swap or is he talking about the distributor?

From the info/knowledge that I have, it's either an injector or a sparkplug. If it's a modular swap...coil is a good possibility.

I just ordered new plugs, coil, wires, cap and rotor. I hope that fixes any misfire I have.

If it still shakes, I think it's the clutch. When I put my trans in I noticed the center weights had a few nicks in some. How? Idk. It could be off balance. But idk why it only does it sometimes.

Also, I'm not too convinced it's not pinion angle related.
