Toyota Shutter Question
I have a quick question I hope...What is the problem when the truck only shutters or shakes over 30 mph and ONLY does it under throtle...as soon as you let up on the gas and coast it stops? Thanks

I agree, could be a lot of things. Hard to tell without being there, but a place to start. Check AFM, TPS for fluctuating or dead readings with meter would be a place to start. Either of these could cause a fuel stutter due to ECM reaction to bad readings.
Just a few suggestions above, post what you find after testing.

Bad front end components, tire rods, ball joints, etc.
Shocks
Tires and rims arent true (round)
I would start by having the tires balanced at a place with a dynamic balancer, a hunter 9000 iirc.

since it quits this after you let off the throttle, it is probly engine related.
perhaps the fuel filter is clogged.
perhaps the plug wires are worn or they are arcing out onto ground

Well, that compression reading is a problem.
I was guessing u-joint, when under load, was binding. Still might be true but you have a known problem now with your compression reading. Fix that first.

if you can, put the truck up on sturdy jackstands, start the engine, let it run, put it in gear, and see if you can pinpoint the noise.
Be sure it's steady, cause if it falls, then it's going right through your garage wall.

I vote for it just being a POS. Only 90 psi is a major problem. Time to rebuild. I wouldn't sweat any u-joint or sensor issues until you take care of the compression issue.

If your compression gauge can plug into your air compressor, then remove the oil filler cap, and the radiator cap, then rotate the engine to BDC for that cylinder, and pressurize the cylinder. Then, listen for air escaping, and look for bubbles.
Coolant = head gasket
Oil = rings
exhaust = exhaust valve
intake = intake valve
