Loping,rough idle

So im new here, but I own a 1996 f350 with a automatic transmission I have changed glow plugs valve cover gaskets and pigtails. I also changed ICP,CPS and IPR. Truck starts up after cranking over a few times then within 5 seconds the CEL comes on and the truck starts to lope not terrible but definitely not normal. Hit the pedal truck runs fine,let off goes back to loping. I also started it and put the truck in neutral and still lopes so assuming it’s not the neutral safety switch.

Does it have a chip installed?

have you performed a wire continuity test to make sure the new wiring is correct and in good order?

Lopeing means the PCM is not sure what to do based on HP oil pressure reported

Did you accidentally wire the pigtails incorrectly?
