I posted this same thing on Yelp, but I mean every word! Excellent service! Very happy with having some much needed brake work done with Your Mechanic and Richard. He updated me on his arrival and made me aware he could come early. I was getting my back brake rotors and pads done, and he informed me that he could get it done 30 minutes earlier than they quoted. He did a great check on the rest of my car and informed me of what I would need next since I have a car with high mileage. With the heat being up to 100 degrees and over today, I felt bad about him being out there and got him a couple bottles of cold water. He didn't complain and he even waited while I took a test drive. Even answered some questions I had about my car without making me feel stupid lol. Best price that I've seen for that kind of work, but the work was probably better than the mechanic that tried to charge me double! Glad to know that you don't have to sacrifice quality for convenience and a better price! Great first experience with Your Mechanic and a big thank you to Richard! I'm recommending him to everyone I know, and I know who to call when I need anything else done!

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.
