There's two 02 sensors right? one for Bank 1 and Bank 2. You think I should replace both right?
whats weird is that, after clearing off the codes from the OBD scanner. I started up my car and the codes didnt show up, I let it idle for 5 min and then went for a 10 min drive and the codes never came back up.
