ok, changed out the other 02 and so far no misses or code. stupid lying SES lights. the code was for bank 2 but bank 1 was running rich by the plugs and 02. we spent quite a few hours on the scanner today and the misses followed the bad 02 and we did a lot of stuff. hopefully it's all finished with.
