CEL (check engine light) has P0136 oxygen sensor code for a while now. Car runs wonderfully. No odors. Gas, mileage or handling issues and light has been on for a while. It sometimes will go off for a while but then comes back. Going to get it looked at. What should I expect they could tell me is wrong as the car has not experienced any problem because of this situation? Thank you.
