my CEL came on today and went to get it checked out. It came up P0141, i believe this is the Heater 02 sensor. The guy asked me if i had any exhaust done, but it's all stock. Any reason why this would happen on a stock exhaust?? Its still under warranty so i'm not upset at it at all, just wondering why this would happen? thanks guys
