Towing the 5er the other day got 45 minutes from home and truck started to run rough. Pulled over was knocking got a p0301 code and and injector 1 has no reading on the balance rate. Truck is back home now and i have been messing with it. Tried the ice pick on injector one didn’t seem to help any. I figured out if i tap the pedal and let it come back down it will show me a balance rate of +14.9 all others are around -4 to -6. Is it electrical? Should i try swapping out the injector see if it moves the balance rate with injector? What are the odds i got some shitty fuel? Or was there some contamination from all the work i had completed Truck recently had the Cp3 pump replaced, y bridge replaced, turbo apart to fix the vane plate and a few other things. Or did I crack a piston. Truck has ran great until this. 2004.5 LLY Dsp5 by Danville Wehrli Intake DHD Y bridge. EGR missing. Run a cat filter no lift pump.
