Hello, new to the site need some help I have a 2002 f250 with the edge juice with attitude, 5 in turbo back exhaust, and Napa filter, I ran the truck out of diesel got it all filled back up and a week later when it warms up the engine light comes on and it takes a dump stays running but acts like there's only four injectors working regardless of chip setting, I have replaced the ICP and pigtail, did the UVCH 50 cent trick they weren't loose but figured while I was there Midas well, also retorqued the rocket arm pedestals and injectors truck is still doing same thing once it's warm it runs like crap and doesn't run good again until it is completely cold, could it be the HPOP or IPR thanks in advance for any advise

 

how does it run with icp unplugged? It could be air in line these things take forever to get air out (could be as much as 100 miles).
