Patrick
27 years of experience
Patrick was both professional and friendly, willingly chatting it up with me about my car. He lowered my estimate because the job was slightly less than what the website quoted, which was nice. While my mount was described as "broken" by another mechanic, he mentioned it was merely cracked and it was up to me if I wanted to get it replaced, which I did anyway because eventually the cracking would lead to a breakage. It was definitely a pleasure to be able to see and talk to the mechanic who was working on my car vs oftentimes where you just talk to the front man of the shop. I would fully recommend Patrick to anyone who needs work on their car and I will go back to him for any work more than an oil change.

First off let me thank Danny for doing such a great job. My clutch feels like butter now (this is a good thing). He called me before the appointment to confirm, let me know of traffic he hit along the way, clarified what I needed to be worked on, and completed the job. Danny is a great asset to YourMechanic!

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.
