okay need some imput once again,
alarm going off at idle only intermittent... reset ket and goes away.... I don't have four tell tale lights only two they don't blink at all.
I see both engines peeing correctly, I feel its the o2 sensor once again.... I have yet to do the service bullentin #56 on exhaust pipes that this winters project... I really don't want to pull it to shop to let them charge me to plug in to see which code only to tell me o2 sensor.
here's where you'll come in I am thinking of pulling o2 sensor on problem starboard motor and switching it with port good o2 sensor ?
I tryed looking back in archives to find symptons of bad o2's in past couldn't find them going by my memory I think this is culprit...
it been a at least a couple of year that I had to replace o2 sensors .
