This was my second encounter with Robert and he's a true gent and joy. Unfortunately, my vehicle's problem couldn't be fixed by him; turns out a new or rebuilt transmission is in my future, but should I ever need YM again, Robert's the guy I want to see tending to my car.

Michael arrived early and finished early. Overall it was a great a experience with Michael. The website needs some work and the support systems at yourmechanic need improving. Also the app that the mechanic had to deal with to update my service order took a really long time. The actual car work was excellent but the overall execution through the yourmechanic systems needs some work.

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.
