Patrick was the mechanic that came out to change my spark plugs and wires and I could not have gotten a better mechanic. It was so nice to have someone who actually took the time to make sure everything was back in the correct place and was running right before he left. I was totally happy with his service.

Jason was extremely professional. He is very good explaining everything. Jason went above and beyond the service and 1) Cleaned the fogged residue on the cars headlamp and 2) check into a noise the car was making and isolated it to right strut. Esp after i mentioned that I just bought this car after getting pre-purchase inspection through YourMechanic. Jason acknowledged that issue should have been caught in the pre purchase inspection. I would be happy to use Jason again.

This was my first time using YourMechanic so I was a little hesitant. But Richard was absolutely awesome. I'll probably request him for future auto appointments. He was here on time for the appointment (in fact a bit early!), and did the job in 40 minutes. All while I was able to get some work done at home. Is this the next big thing in the DMV? Cause sign me 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.
