Chris is the real car god not the other guy who claimed he was and literally destroyed my car. I was with this guy when he started working on my car until the end and I can tell how experienced he is. He came did his job with compatency and more than that, he fixed the other guy's mistakes. He works with passion and treated my car like his own car. Basically the best mechanic in this company.

Jonathan was just AWESOME on the service (oil change) he did on my BMW. I am truly impressed. Any other service that I would need with my bimmer, I am gonna ask for him. After the oil change, my car had a oil leak and I got my Brake light and Check Brake fluid light. At first I thought it was due to oil change. Later Jonathan came back again the next day and identified the it was brake oil leak. He got the place of leak within few minutes, which no other mechanic could do. This guy knows so much about German cars. Glad to have got him work on my car.

Carols was helpful, honest and pleasure to work with. He gave me a hint of what to do with my car from this point because it does need some work. I was happy because he gave me a couple pointers on how to get my car fixed with paying a lot for it.

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.
