This is my first post so here it goes...
I need help with diag I have a 2006 6.0 f350 with p max 5" exhaust . I bought the truck wrecked hit in the front and had a dent in the oil pan also broke the upper oil pan that the pick up tube bolts too. It had oil in the pan when I got it started and ran fine.fixed the truck noticed it had a miss would shake or miss violently in overdrive at 55 mph or more especially when going up hill. Did a contribution test with my souls scan tool and said cylinder 8. To confirm this I took it to my buddy's shop and he used his vcm2 to do a power balance test I believe that's what it is called and it showed 8 down big time. So I changed it idles fine but miss was there at 55 in od so I we scanned it with vcm2 again and it showed 2 and 6 down at 55 when it would miss. So in short I decided to change all injectors, motorcraft, updated oil stand pipes and dummy plugs. Fuel pressure is good holds 62 at idle and about 55 at wot. Changed all filters more than once with motorcraft. Ficm voltage never drops below 48.5 icp with Eric's sct tune was commanding 1750 and the lowest it hit was 1550. It's very unpredictable one minute you can do a pull from 0 to 100 not a problem the next it will act like its running on half the cylinders. I had Eric put the truck back to stock so I can observe my icp easier. Any help would be very appreciated. Also I have asked a lot of people about this but I found two t15 torx in the original oil pan!!! They were broke off too.
