i left the house today to go to into town and as soon as i pulled out my truck started running like crap the check engine light came on and it sounded like it wasnt getting enough fuel and it was running real rough then i let off and it ran fine and then when tried to go again it started running like crap again well i ended up turning around because it wont stop running like crap period even when i do let off or put it in park..and when i try to accelerate it does but very very slowly ..its done this before but it would only happen for a few seconds then it would be fine..

i drained the fuel bowl before i turned around that didnt do much and when i got home i had enough time to check the oil and it was good..

idk if its a sensor or something to do with where the wiring harness goes into the injectors or what.. idk its pouring down rain so i couldnt mess around with it..

and the last time i drove it it ran fine.. the only thing i did was changed tanks on the way home last night so that could be the problem but im not sure cause today when it was acting up i switched it back and it didnt do anything..

maybe you sucked up some gunk and clogged your fuel filter. if that happened then changing back to the other tank wouldnt do you a damn thing.

well i just changed the fuel filter and put diesel clean in the fuel and still running like crap so i started looking around and i pulled the wiring harness plug going to the front left injectors and one side of it was burnt up so im gunna make a guess and say it has something to do with it running like crap

im hoping its the same thing that happened to my 95 f350 and i had to replace the wiring harness both valve over seals and the wiring harnesses that go to each injector under the valve cover

yep sounds like a valve cover harness issue.
