Without a doubt Michael is the best mechanic in Charlotte!!! He showed up an Hour early for my appointment because he knew everything I was going through was last minute and wanted to get to me as soon as possible!! My car was stranded at a friend's house and was not there when he arrived but he basically completed my service by the time I had arrived (still 40 minutes before my scheduled time) and was nice enough to look at my friends car while he was waiting on my keys to finish up with my appointment!! My friend needed almost 3 bottles of transmission fluid because it was so empty and Michael happily filled his transmission with fluid he had on him...Free of charge!! And diagnosed my friends car with his recommendations for that as well. Honestly can not say how how I am Michael is my Only mechanic!! He is probably the nicest guy ever, comes Fully equipped with everything possibly needed for mechanics, is extremely informative, best person I have met at timeliness, and is 100% trustworthy!!! If you have the luxury or getting Michael consider yourself lucky!!! Great great great guy!!!!

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.
