7.3 NO power, rough idle sounds like it's missing

LONG READ
So long story short I've been at a loss with my 95 7.3, it all started in summer when It randomly shut off and wouldn't restart, after checking many things it decided to finally fire up and run, I still don't know what I did or why it fired. Well it was running really rough so i took the valve covers off and some injectors were squirting oil and some weren't so I decided to buy swamps baby swamps injectors because I thought this might be my issue. Well now the inctors are in and I got the truck to fire and run okay for a little bit, i decided to take it for a test drive and it has NO power it will barely move on it's own and sounds like it has a real bad miss and is idling really rough. Any ideas? I have checked the hpop and it's making adequit pressure, I put one valve cover gaskets on the side I thought was missing and it didn't change, I put a known good idm in it, it has adequit oil in it and it only have 500 miles on it, it has a regulated return and is making 70 psi of fuel pressure so that's adequit. There are no check engine lights and it is not smoking at all. I just rebuilt the motor last summer and it was running great with no issues before it shut off. I'm at a loss and running out of money to just throw parts at it I would appreciate any help.

Re: 7.3 NO power, rough idle sounds like it's missing

Has it run long enough to get the air out of the fuel and high pressure oil systems? They will run like crap till all the air is purged out

No, there is more than likely air in the oil system but it is running the same as it did before I changed the injectors. I can start it and idle it but I really can't actually drive it on the road because it will barely move even when you put the pedal to the floor.

Yes, except the number 1, it's not spitting oil like the others, its only dripping a little bit.

I think I would put a guage in each head and check oil pressure

I had a gauge on it before and I forget the exact pressure but it seemed like an adequit amount. But might not be a bad idea just to re check.

IIRC it needs 500 psi to start

It had well over 500, it'll start and run just rough.

Was the guage holding steady pressure.
