Daily Life and Compromising

Sorry you are feeling so bad.

"Engine codes say 2 injectors...probably going to have to have them replaced around $500-700 and ask my family for help paying for it."

Before doing that try running a tank or two with injector cleaning additive like Techron D. They are more likely to have built up deposits than to have failed especially if the previous owner was delinquent with fuel filters. I was a mechanic taking care of 30 agricultural diesel and never had to replace an injector for failure. Not to say it can't be, but $15 of additives may save you $700 of repairs. In may seem worse at first but that is proof it is doing its job.

Tried this once, doing it again but put 7 cans of seafoam in with 30 gallons in the tank left (3/4 tank), it stops the rough running for a bit and extends run time before it starts running rough and showing the obvious power loss of struggling to hit 50mph. BUT the engine still runs in "limp mode" with a limit of 65mph.
BTW it is a 2011 Ford F350 6.7L Diesel with the Ambulance Package, >,< the previous owner never even knew it had a fuel/water separator and he never drained it so I think it got water in the system at one point.

Dumb question: have you tried a different brand of fuel. Back in 1984, Oldsmobile Cutlass had injectors that would clog up specifically customers using Exxon gas. The next year GM changed the injectors and the problem went away. Here's a fun video from Open Original Shared Link

Truck Update, Took it to a mechanic and found it has low compression on those two cylinders so not a injector issue. The mechanic said we needed to change the engine to a 2015 model, saying the early first gen motors had issues with glow plugs breaking and locking up and breaking crankshafts. Unfortunately I do not have the money for a 7-8 thousand dollar motor and the labor to fix...I checked the wrecked used trucks sell for 10K Plus so no donors.
My bet is to pull the head and have my fathers shop do a valve job and surface it....but now need to find someone to pull the head.....that last guy after he "tested it" it came back to me and now misfires and the whole truck shakes, no longer trust him.

Easy and profitable for him. No wonder you don't trust him. Maybe he broke a glow plug and is CYA. If he got air in the injector lines and did not get it bled out or left one or more loose it could cause the shaking. If air in the lines and not leaking it will eventually self bleed and you are back to where you started. If a line is leaking, it won't. "Look where hands have been." Which cylinders? New codes and which codes exactly?  Did he do a second compression test with oil or a leak down test? That would differentiate between valves or head gasket or piston rings. Head gasket leak between two cylinders without coolant involvement could explain the low compression on adjacent cylinders. I had that on all 4 cylinders of my son's Matrix. Was recommended to replace the engine but it was only head gasket leaking compression between the cylinders. I fixed it with a $30 gasket and my labor instead of an engine swap.  What color is the oil. Milky? I'm in Florida so I can only offer words to help. If leaking from ring wear I think it would effect all cylinders to some extent. So, unless the pistons or piston rings are suspected of leaking or broken (glow plug damage); pulling the heads sounds like the next logical step. By the way, if broken glow plugs was an issue why not upgrade them or the heads? Does not sound like a used engine swap is appropriate to me. You might end up with someone else's problems. As Adrian Monk said, "I could be wrong, but I don't think so."
