Just wondering: how many miles do you have on the oil? It does take a long time to purge the air out after you change injectors, but if you are getting any air in the oil (like foaming from lots of miles on the oil) it will most likely never really purge. These engines really do need the right oil (think about how the injectors work, they are very hydraulic) and I've seen more than one no start powerstroke fixed with an oil change.
If it's pretty fresh don't give it a thought, but if it's been in there many moons, or it wasn't diesel specific oil, it could be your issue.

It's changed often. I had changed it recently but I will change it. Stupid to run used oil through new injectors anyway. Sounds even dumber when I read it.......

Got it to fire off and run. It's still not right. It will rev up. Only clears up at 1300 rpm and up. Will idle but rough. Won't rev down to an idle but I can start it with no throttle and it will idle but rough. I have had a bit of experience with gas motors and it acts alot like cam/ crank sensor correlation.

Give it more run time.

Ok I'll run it more. Should I leave it at idle or give it some rpm?

Higher rpm.
If can keep it from dying, some wot runs should clear it out.
But.... it's possible you have a few injectors not firing.

I rebuilt them. All within tolerances. Everything should work. Never imagined it would take this to purge.

That doesn't mean everything is a-okay. Especially the wiring.

New valve cover gaskets and harnesses. Might not matter but I did replace them. Just tried to crank it. Wouldn't fully start. Still got air?

Sounds like it.
What brand harnesses? Dorman are known for issues right out of the box.

Don't think they are dorman. I'll see if I kept the boxes.

Ok, got it to fire again. Ran it for half an hour doing some WOT hits. Clears up over 1500 rpm. I let it idle for ten minutes. Still idling rough. Stuck my hand in the front wheel wells driver side was pretty hot but passenger side was cold. Put my hand right on the manifold on all four. Cold. I thinking I unplugged the injectors with the valve cover or the injector harness is junk. Thoughts?
