6.0 problems

2003 6.0 is acting crazy again. Has new ICP, IPR, oil discharge tube, and hpop. It cranks right up but one time you crank it and all the gauges work correctly, especially the fuel gauge. The engine will idle perfect but when you accelerate it has a dead miss. May crank like that 2 to 4 times. Then you crank it and it runs like crap, and the gauges won't work, the fuel gauge goes past E and the light comes on. As long as that happens it runs terrible, but when the gauges are working it idles great but has a miss under acceleration! It was running fine, then just went nuts! Any ideas would be greatly appreciated!

Harness chaffing is part 1. Once that's addressed there might be an injector or two that are not working.

With the holidays and the nasty weather, I haven't been able to check it yet but I have a guy that's supposed have a tool to check the injectors with. Thanks again guys, and Happy New Year to y'all!
