I could not be happier with Ben's work. He himself was professional and on time, but most importantly he did the work properly. I have sought automotive repair and maintenance from many sources including multiple dealers and I keep finding crooked and/or incompetent work being done, so it is a relief YourMechanic connected me with Ben. Having him come by and work on my car while I take care of my 4 month old and 3 year old daughters was a very big advantage, but the most important asset he brought was his decades of expertise in mechanical engineering. I cannot emphasize enough how hard it is to find someone who actually knows what they are doing. In the midst of a growing family and the responsibilities that come with it, having an honest go-to guy to take care of a large asset like my car is a huge relief. He helps me take care of my other baby.

Dave was on time and called to provide ETA before arrival. He diagnosed my engine vibration to a ignition coil and also low on oil. It's funny that he has to book himself via the app for the parts replacement to work within yourmechanic system. Picked up a new ignition coil and fixed my car on the same day and even went a step further to pick up a quart or oil and top off my low oil.

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.
