04 Powerstroke 6.0 misfire

[veedubmechanic]

I have this 2004 Ford f350 powerstroke diesel in the shop now 5spd manual
It had codes for the crank sensor p03?? and p21??, and cyl 1 and cyl 3 imbalance.
It is definately misfiring at idle or giving it gas but when the revs come down its fine and smooth. I replaced the crank sensor and MAF sensor(burned black and full of debris) and it idles alot better now but still misfires. I replaced both fuel filters 500 miles ago added diesel fuel cleaner and changed oil with castrol diesel 15-40 synthetic.
With the scantool I did a injector buzz test and it passed with no codes.
I did the injector dropout test and every cyl runs worse when the injector is cut out.
I did the glow plug test and it passed with no codes.
I pulled the glow plug harness on the passenger side (1-3-5-7) and the harness ohm out at .04ohm for every plug and they look fine not melted. The glow plugs are also ok and look fairly new.
The truck misses hot or cold.
When the truck is not running it smells like clutch material arround the turbo by the back of the engine. Before the truck started missing it drove fine and did not miss or have any clutch slipping issues or chattering. I do not hear any dual mass flywheel clunking either.
I dont want to condem the injectors in 1 and 3 but I dont have access to a diesel compression tester either.
Also when its warmed up and you rev it and it comes back to idle it chugs and seems like its running out of fuel and then when it dies it is very hard to restart, but one it starts it runs smooth as glass for about 10sec before running rough. ????

ANy help or hints? there are no specs for injector resistance online!

Needs two injectors, EGR cooler is probably blown, You can check by pulling the EGR valve out and see if its sticky, if it is, its blown, if its hard and dry its good.. Mpre than likely needs head gaskets if the EGR cooler is blown.

Its going to pass buzz test because the electrical part is fine, its the valve inside the injector.. Electrical side wont never throw just an contibution/ balance code, it will throw an high to low side open code.
