A lean or rich bank code is either a bad 02 or incorrect tuning. If your compensation table is not setup correctly you can easily get those trim codes. A bad 02 will also cause the engine to trim outside its limits and cause the code. I would log the car, easy way to tell if its a bad O2 is just compare the trims on each bank, if they are reading roughly the same then its a tuning issue, if one is consistently reading wacky then its an O2. Like I said earlier disconnecting the O2s is almost needed because mine one bank would constantly run rich even tho the target was 14.7.

I would love for a pro tuner to chime in just to see what tables they have access to that none of us do. I know Megan has it on here.
