Patrick did a great job he is a very well qualified mechanic. And he is most pleasant to work with very courteous and helpful. We had one oxygen sensor that the GM company sent us that was the wrong plug and part. Patrick noticed it right way and I had to reschedule him to come back when I receive the replacement.

Matthew

Matthew is a true professional. It was like having a personal mechanic. I wasn't sure where the issue was regarding my brakes (front/back, pads or rotors). Matthew walked me through potential issues and told me he would only do the work required. He found the issue and identified a major safety concern with my brakes. He allowed me to see for myself what the problem was and described exactly how the work would be done. It was reassuring knowing that I could get a professional mechanic that can solve my brake problem at my convenience and at my home. I would more than likely use Your Mechanic for my auto service and definitely request Matthew as my auto professional.

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.
