Lucas

(see previous review) Lucas came back to my house to re-replace a part: he discovered a more updated version of the ignition coil existed. He arrived early, replaced the part quickly, and gave me a verbal run-down of all of the work done on my car (and what to expect into the future). Officially making him my personal mechanic from here on out!

Tom

Had an amazing first experience with Tom. I've already told my neighbor, my brother, and my Dad they need to start using him. Did an incredible professional job, even stepped me through the process so I can do it myself next time. It was very reassuring watching Tom work and seeing everything come apart and put back together with the new parts. YourMechanic is the opposite of everything that is wrong with the typical mechanic shop. Car drives perfectly now and buying my own parts and having Tom install them saved me a big chunk of change.

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.
