I have a 2006 f250 6.0 203,00 miles. At 196,000 miles turbo went out, bought power max turbo, redid head gaskets with studs, had heads shaved flat, replace oil cooler with ford part, egr delete, custom tune, aftermarekt 48 Volt FICM.

Truck ran great until 1 day didn't start. had to let truck cool down and then it stared oil pressure was only going to 350psi. drove home fine, shut it off and wonted start hot. drove it a few times after that just let truck idle. Then it started to crank longer when cold. Replaced dummy plug and stand pipe on drivers side only. Then truck was ok for a few drives then started to get a studer sometimes when idling. It got worse then was getting a misfire cyl 1 then, truck died 1 day turning around and would only build a 200 psi.

Replaced stand pipe and dummy plug on passenger side, and IPR, now getting misfire on cyl 8 and P2284, truck runs like crap, bad idle, rpms weird/gas pedal. idle is higher than it should be. when truck is first started shacks very bad, engine very nosiey. ICP 1046 psi(1.27Volts)Desired 637.9, idle and ipr 14.84, truck idles ok, when u punch gas revs up and comes back down, misfire gets worse with rpm.

Then icp goes to 870(2.23 Volts)Desired 870 and doesn't change when getting on the gas and ipr 32.42, punch it and rpms go up more then come back down. Truck starts to shake again. Could running it for so long with bad oil pressure or to much air wreak the injectors? When cold can shut off injector 7 or 8 doesn't change idle like all others do. Once warm 7 or 8 does make a small change in idle. If i command ipr to 20% idles fine, but icp no change from 32.42% to 20% Thank You

 

I got it figured out, it was a junk IPR, was brand new from ebay, thought it was a ford part but now found out it was ATS. Don't know if it ever worked correctly. Have not checked injectors yet.
