Mr. Phan was early to his appointment and fixed front and back brakes while my car was parked at work in about an hour. He was very polite and professional and now my brakes do not squeek when I apply pressure. He was so honest he told me my back brakes did not need to be replaced but I told him to do it anyways because I thought it was a good idea since I have never replaced them since I have owned my car. This is my second time using mobile mechanic and I am very pleased with the pricing structure and level of professionalism. I would definalty reccomend this service to my friends and family.

This guy is a car genius or something. He had the front brakes and rotors replaced so fast that I barely had time to finish a glass of coffee. On top of that he noticed about three other issues that will break sooner or later - no pressure, just pointed them out. I feel sorry for those suckers stuck at Pep Boys and places like that.

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.
