As stated above you have a bad O2 sensor. Low voltage represents a lean condition while high voltage represents a rich condition. If you are at 950 and not fluctuating then you are dumping a lot of fuel and getting horrible gas mileage not to mention your catalytic convertor is going to become destroyed soon. I recommend you replace both O2 sensors. Reason being you want both sensors reacting/fluctuating at the same rate for the optimal air fuel ratio which affects gas mileage and performance.
