I travel a lot and my gas seems to be just as good as when I bought the car. I do all the routine maintenance. Could this just be due to a faulty o2 sensor? Also could I get it checked at a smog place and tell me if the o2 is bad or the cat itself. Thanks. Any home tests as well. (2.4L, automatic, SE model, japan.)
What is the typical problem if my 2002 Toyota Camry gives off a code P0420?
