Alright so I've been messing with a buds lly for the past 2 months now. He had the old crappy edge on it before I installed a dsp5 and efi tunes. Ever since then the truck will just randomly run like crap from throughout the injector harness codes ( can't remember the codes but its injector #2 and #7. Sometimes different ones) but the I've done the ice pick on them all and replaced #2 and #7. So I don't think that's the problem. I'm thinking its wires somewhere else. I checked the wires coming from the FICM that go across the sharp bracket and they are fine there to. Any ideas? Batteries have good connection. Tool it to the dealership and they got the same codes thinking it was the injector harness. But said they could find anything wrong with it. Also it has a new FICM. Could I have bent a wire unplugging the old edge? Or dsp5 switch cause this from not getting good connection? Will be looking at it on Friday. Putting the upgraded injector harness on it.
