Guy was very professional and knowledgeable. He completed the work in half the time I expected him to. At first, I did not believe him until he showed me the parts that he replaced.

I am so happy about my experience with yourmechanic.com. Casey was very knowledgeable, communicative, and professional. The cost of the work done was much lower than what I had been quoted at the repair shop. One thing I especially liked about Casey, was that he seemed real about what needed to be done ASAP and what I could work on at a later date. With other places, I feel like they word things in an alarming matter to try and get me to do it all at once, which I'm just not able to afford. I hope I have more experiences like this, as I will be booking all of my work through yourmechanic.com from now on! Thank you!

From the moment the appointment was scheduled, I received phenomenal service! YourMechanic maintained consistent effective communication with me about my appointment and worked around all my issues, to include car being parked in parking garage, work schedule, not having consistent access to my cell phone due to security of building, etc. GREAT SERVICE! Eugenio arrived in a timely manner and utilized my requested means of communication (office phone). He met me in the middle (worked on my car in a street parking spot). He effectively diagnosed the issues and fixed the problems in a timely manner (total time to completion = 1 hour). I couldn't be happier with the way things went and I spent less than $100 on the amazing service. WILL DEFINITELY be using YourMechanic again in the future!

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.
