I had an electrical problem with my car (wouldn't start). I thought it went beyond the typical dead battery situation (battery wouldn't take a jump, there were no preceeding hard starts), so I wanted everything tested. It was convenient to have him come to the car, instead of me taking the car to a shop (since it wouldn't start, we were probably looking at towing). I could have changed the battery out myself, but I wouldn't have known if there was some underlying issue or not (starter, generator, alternator). It turned out that it just was the battery (battery was bad, needed to be replaced), although Lucas tested everything, so now I have some peace of mind that it's not going to happen again.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
