He was very efficient, strait forward and I felt like he was honest. He fixed my car so I could get it off the street and he gave me recommendations to prevent the problem from happening again.

Shaun did an excellent job! I needed an 80k miles maintenance service and since the service was expensive, I wanted to just get an oil change and get his opinion on what services were needed within the long list of Mercedes recommended services. I handed him the keys and went back to my office. He finished the service within the allotted time and let me know what services I needed with a detailed report of my fluid levels, etc. All of this and the time needed from me - no more than a couple minutes of handing the key and taking it back after the service. Convenience at its best!

WOW!!! I loved the experience of having a mechanic come to my home. He arrived promptly, introduced himself and got right to work. He took his time to explain what he was doing, and answered all my questions. I was so surprised when he told me the repairs were still under warranty (my car is 7 years old/67,000 miles), Wow, now that is a honest mechanic!!!! :) I highly recommend "Your Mechanic".

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.
