The oxygen sensor reads the amount of oxygen in your exhaust to calibrate your air/fuel mixture. If it reads a higher voltage, the sensor is telling the pcm that you are running rich. Your sensor could be bad or need cleaning. Start with the inspection of the oxygen sensor for carbon deposits and the wire for any pinch or melting. Since it is a 97 you probably need to replace it anyways.
