G8 PCM, how can you have triple fuel on one bank with 0 fuel trims Running 17 ms at idle on bank 1 and 5 ms on other bank, at 0 fuel trim short and long terms. How can it be affecting fuel on one bank vs another still in openloop and no fuel trims? If you start it up they are even for first second or so, then as it runs the pulsewidth gets higher and higher vs the other bank on Bank1 till the point you can hear it misfire and sounds like it drops the cylinders in that bank.
Doesnt straighten out until you go WOT and get into PE mode, it was set to enable at 3000 rpm stock on this file and soon as it gets there the drivers bank goes to normal with a tenth ms or so of passenger and motor sounds clean. Yep, cleared fuel trims was first button I hit. Longer data looks the same, doesnt do anything differently. The other thing it was doing was setting a P0333 code knock sensor bank 2, but turned all timing retard out of it and deleted code just to see what it did and no change to the fueling issue. Not sure what knock sensor acting fool too, but thats secondary issue to this?
