A litte help

My Dad left me his 94 f350 4x4.Its got a little issue I cant figure out. its only got 100k on it, and has been very well looked after, the oil was changed religiously.
When its completely warmed up..like after a run on the highway, it will start to miss at low rpm..(like when pulling away from a stoplight) It shakes and has very little power..after 1500 rpm it seems to straighten out...

So far I have changed the oil (twice) fuel filter, cam position sensor, icm, glow plugs and wiring harness, valve cover gaskets, and glow and relay...Am I looking at injectors??? Any help would be appreciated...

im leaning towards an oring issue here, does it smoke in the mornings at all? cold start that is. if it does then ill say its an injector oring issue. if not then ill say IPR orings, 18$ quick fix.

I'm just thinking of things that can be checked with out spending $$$ but it could be one of those

Did you clean the FPR screen in the fuel bowl

i still think its an oring issue, i know with my old red truck it was a bit skippy when warm, added a chip and it went away, i knew it was my orings thoe, the added injection pressure masked the issue for a little bit.
