last night i was driving home when out of no where my cel comes on and my truck sounds like a train idling rough shifting hard just weird stuff so i limped it home and started it up this morning and it idled fine so i took off down the road it sputtered for a second now it runs fine it was raining last night so not sure if that might have anything to do with it being fine this morning but i ran the codes p2146 fuel injector group A supply voltage circuit open, p0204 injector circuit malfunction cylinder 4, p0206 injector circuit malfunction cylinder 6, p0207 injector circuit malfunction cylinder 7 thanks in advance guys

Sounds like ya need to try the "Ice pick fix"

That's kind of what I thought but from what I read I thought it only happend to the number 2 and number 7 cylinders plus the fact that it happened when it was raining and not doing it when it's not leads me to believe that there may be some exposed wires or something but then again I may be totally wrong and the ice pick is the way to go

Harness could have also rubbed through where it goes over the alternator bracket? I believe is another common problem

Yeah I remember reading somthing on that I'll take a look and see if anythings AFU

From what I can tell the wires didn't have any rub through so I'll give the ice pick a try
