Dave is the man you can trust! Replaced my front brake pads and rotors in about half hour. When I ask him about the problem with my HID headlights, he is so nice to guide me to buy bulbs from amazon and when delivered I can schedule with him to come and replace the bulbs. A nice thing with YourMechanic is that, you will automatically get assigned with the same mechanic when you schedule services again with them, because you've built connection with your mechanic, assuming the connection is good:) It is so great to have Dave as our mechanic.

Rob was polite and professional, but relaxed and friendly. Told me about his experience and why he is working for Your Mechanic. Showed me how the brakepads are measured and showed me the worn grooves in the rotors. He was efficient and was a good sport about having to work in the sun on a hot day. Two thumbs up!!

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.
