So you replaced the O/2 sensor? It sounds like you may need a fuel filter. The codes you listed are oxygen sensor. If it is a rich condition it may be as simple as changing the air filter. If it is a lean condition then it may be as simple as a fuel filter. The 131 code is a low voltage (Bank 1, Sensor 1) The 132 is a high voltage (Bank 1, Sensor 1). Did you check the wires going to the O/2 sensor plug? What was the part you changed?
