07 6.0 powerstroke
 

I got an 07 6.0 powerstroke with 117000 miles on it.
the truck has in the last 3k miles: Egr delete, new oil cooler.
was driving the truck and it died. would not build high pressure oil. Pulled IPR valve found hole in screen. heres where the problme comes in. The truck ran and drove just fine. I replace the high pressure pump and ipr valve with factory ford parts. started truck and now is setting random cylinder contribution codes and runs rough. i double and triple checked all my electrical connections and not a clue what to do next. only ran the truck for about half hr at idle and shut it off. Could air in the system be causeing the injectors to not fire correctly. and by the way it did get a complete oil change before starting. truck didnt crank long before it fired up. i just dont understand why all the contribution codes and running rough now. any input would really help. thanks.
