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.
