Joshua was great. He arrived early which was a plus. He quickly resolved the problem and ordered the parts. I would recommend him to everyone. As a matter of fact while he was there attending my Mom's car, I had him to look at my car as well. He was wonderful and very professional.

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.

Clarissa is a real professional, from her diagnosis to her work. She worked on my car at my job, I can't tell you how convenient that is for me, a single mom with a special needs child. She made sure I was charged only for the work that was done and she did a great job on my car! Thanks Clarissa!

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.
