    Comments about Bosch Oxygen Sensor:

    The car was running bad before this sensor was put in. After I can see a huge difference in the sound of the engine when idling. I also notice better throttle response when I put my foot on the gas pedal. This is easy to install if the oxygen sensor tool is used.

        On the SOHC engine the front (A/F) oxygen sensor is located in the front section of the front catalytic converter. The rear oxygen sensor is located in the rear section of the front catalytic converter. On the DOHC engine the front oxygen sensor is located in the front section of the exhaust system, just past the crossover pipe. The rear oxygen sensor is located in the front section of the catalytic converter.
