    Ordered my 02 adapter from Keith and installed it last night. Erased CEL and checked codes...both 02 related....CEL went off last night and came back this morning. Any thoughts on a work around? Or am I just stuck with this? TIA, John

    IIRC you installed new exhaust/headers?

    Sorry, my bad. Yes, Keith’s exhaust. Got the O2 adapter installed, cleared the CEL, and it came back. Think codes were 0076 (or 56) and 0430. Both oxygen sensor related. Figured that since the sensor was just tied onto the pipe with baling wire, that’s what was kicking it off. Maybe time for a new sensor?

    Give it the test. In red were my o2 Sensor readings. The rears were dead and no CEL. Fronts were Bosch and below Spec and no CEL.

    Gonna do some tests this weekend on the sensor and then give Keith a holler next week if I find nothing wrong with them. PHM really has some good info there, thank you much for that!

    Did you splice the wires in? or did you do a complete harness swap?? Its possible that the connector is not plugged all the way in, or the splice has been undone, or have been damaged.

    Are there any air leaks in the engine bay???? May be push in all air hoses to ensure one didn't come loose on accident.
