Tien was fantastic and helpful! Very friendly and professional and put me at ease regarding my car troubles. I have gone thru so many mechanics that steered me the wrong way and making me pay for things that weren't the right fix costing me unnecessary repairs! Will definitely call on him for further fixes on my 2005 AWD Saturn Vue!

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.
