Tom is officially my new favorite mechanic. He came to do an oil change and tire rotation on my mother's car on a Saturday morning. He arrived at 11:00 on the dot ready to work. Very friendly guy, and we learned that he was a mechanic at Audi for about a decade. I love that he didn't talk down to my mother or me for being women, explained any issues we had and I could tell he really knew what he was doing. What a big difference from the last mechanic I had! Since the last mechanic that came left my car in a bit of a mess, I asked if Tom could take a quick look at mine as well once he was done. Being off the clock by then, he happily agreed to take a look. What an honest, great guy. On a Saturday, too! One quick look and he could tell the last mechanic didn't put my filter on right and that's why oil leaked everywhere..this is why it's important to look through reviews before booking your mechanic. I'll never use anyone but Tom! He's efficient, friendly, genuine and very good at what he does.

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.
