ok so my car has had the CEL on for a week or so now and i have thrown it on a scanner and cleared it a few times but it keeps throwing the same codes. Since i put my o'r x pipe i put the MILs and this is the part i dont get. its throwing codes about 02 sensor 2 bank 2, which is the post cat passenger side right? but i dont know why it would be thowing codes for that sensor if the mils are on? unless i burned a wire maybe? idkk ....
