Hey all, since I've bought my current LS i had multiple codes for o2 sensor bank 1 sensor 2. Replaced it and now im left with P1151. I've searched on the boards that lead me to check for vacuum leaks of which none were found using a smoke machine. I need some advice on how to trouble shoot this code or a potential fix so I can be able to pass NY inspection. Thanks.
