my car has been throwing a bank 2 snsor 1 code and a system to rich code. the people at advance told me bank 2 is passenger side but a lot of people online say driver side so i replaced the dirver side and the same codes came back. Ima switch the left and right sensors tonight and see if the same codes come back of if bank 1 codes come up. It started throwing codes the day i got it back from a shop that pulled the trans and replaced the clutch so i was wondering if theres a chance they accidently pinched a wire or cut one. When im accelerting gently it feels like there is a miss and going at a constant speed it runs pretty rough but if i step on the gas harder it runs great. if i clear the codes it runs perfect for about 25 miles and then the code comes back and it runs crappy. im getting sick of the codes so any ideas or advice would be greatly appreciated, also im getting TERRIBLE gas mileage
