Yeah it has a Bosch now, so the batt was 12.5 and running it was 13.9. Can't find a battery ground cable locally that's stock so I'm making a heavy duty one

no napa store near you? even advanced or auto zone should carry, them,. a 13.9 reading is pretty weak for a bosch alt, its possible to refresh it, but not that a refresh of a new voltregulator and a clean up will get it working better for longer,. my alt(s) right now i picked up are bosch alts, rebuilt by remey, they put out 14.3x volts, at full batt charge, (thats fresh of course).

I will build some new grounds. The battery 12.5 at rest and 13.9 while running I think it's all the grounds. Even though I cleaned them it's still the old copper braided wire.

new grounds, and/or battery straps, are cheap investments for reliability. adding new grounds, esp the motor ground (to body), also pay off well, i added new hot charging wire too. clean stuff up. you can also check your voltage drop when you finish cleaning stuff up, theres a link somewhere in faq.

Sounds like you got a handyman special. You're gonna need a Bentley Manual.
While the engine is running poorly, you can slightly loosen each injector fitting in sequence, to see if there is one that makes no difference... at least you could narrow to one cylinder.
Possible you have a bad valve/lifter, or bad injector. Maybe as simple as a missing injector heatshield. More rare would be something funky in one port of the IP.
I'd suggest getting the Bentley manual, putting clear lines in and out of the IP, getting an older style fuel filter that has no plastic tee pre-warmer and get some vw diesel timing tools.
I concur that if you experience excessive torque-steer, the control arm bushings are bad... the loaded arms are cheap enough to R&R without pressing the bushings in.

It ran absolutely fine in the morning after I charge the battery I think the drive going into my work which is about 30 miles out with the heater on the lights on and the fan working I think drain the battery down a little bit plus I didn't get the normal squeal I normally get from the alternator when the battery is fully charged and these things didn't start until the belt broke and I drove back from work. I'm really leaning towards alternator so I ordered a new alternator. I'm going to replace all the grounds with new cables

Last night I ran a 14 gauge ground from the top bolt on the alternator straight to the negative post on the battery and I ran another wire to the body. It was at 13.9-13.6 volts. Full load with lights and heater on its at 13.5-13.6. Like I said it runs decent when cold but when it's warm after a extended drive it shakes and shakes violently when I turn the wheels. It goes away if I drive with the cold start on. Comes back when I push the cold start back in. Squeals everytime I start it for about 40 seconds and it didn't start doing this until after the alternator belt broke and I had to drive 50 miles with no alt

Replaced the fuel filter. Bubbles in the lines during idle and get bigger when I rev. I cracked all the injectors and the all effected the engine Rpm's and made it run rough. So it lookalike in cutting some hoses down to redo connections and blow some compressed air down the lines

Sounds like a good plan. Not uncommon to have vacuum building up in the supply line if it is restricted.
