2005 SL65 AMG
P2097 and P2098 at the same time (all the time)
I have an 2005 SL65 AMG. I've been getting both P2097 and P2098 codes. Both are post-cat fuel efficiency related, one bank too lean and the other too rich. Dealership said my cats are good, so we replaced all four O2 sensors, and the codes came right back. There are no issues driving, no rough idle, no misfires, just these same two codes keep coming back. The dealership had the car for about 6 weeks and never could figure out the problem. Has anybody else had this issue (and solved it) ?
