Re: My 4.3 has a miss
why can't I hear about this stuff when I'm at work? you have my # Larry (guilt trip)
IIRC the P013X's are O2 related. P0135 is O2 1-1 not switching, I think.
at first you said you have sooty plugs on bank 1 but later you show a code P0304 (cyl 4 miss). I would be curious to see what the missfire counters are. sometimes a cylinder after the one missing can show as a miss, ie. #5 is missing but #4 is counting.
all 3 on bank 1 leads me away from an ignition miss. I would have to see the fuel trims to be sure. I am thinking you may have a leaking fuel pressure regulator.
I will talk to the warden and see if next weekend I could take a trip and bring some tools/scanner. BTW, I need to stretch the legs on my Kaw. NO, I will not have room to bring a muffler back with me. LOL
