Went and changed my O2 sensors today. Old ones were original and used extensions when I did LT's. my rear ones were tuned out. Well when I went to remove them I saw that one was plugged into the rear sensor plug. Other one was plugged into the front correctly. Must have happened when I had my trans done. I drove it all last summer this way. Never had a SES light or had a code pop up. I even checked for codes last year just for grins and there weren't any codes. Seems very strange.
