Joshua was able to come earlier than we had booked. He was very professional and polite. After he backed my car out of the garage, he went right to work. I checked on him once and I was very impressed how neatly he had his tools set up. Not only did he replace my front brakes, but he gave the car a test drive, checked all the fluids and put air in my tires. He told me loves what he does. He showed me pictures of the work he had done. He took photos with his iphone as he did the work so I could see what he had done. That was a first!!!

Peter was great. He is very knowledgeable, diligent, honest and trustworthy. I was definitely skeptical at first, but this is a real-deal service offered at your convenience without having to pay the over-head costs and scams associated with brick-n-mortar shops. I don't freely pass these out, but I highly recommend both Peter and Your Mechanic Services.

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.
