ok guys, check engine light came on, so i pulled the codes myself and i got P0136 and P0141, i believe those are the 2, i found some info on it and its says " Bank 1 Sensor 2 failure" ne ideas on why htis might have happened? and can i buy the MIL eliminators to fix this problem, i had the front 02 sensor replaced on the passenger side this past sapring and im not sure what they call that one, help always appreciated
