Tien

My first time using this service was on March 11th, my power window motor and regulator went out so I ordered the parts online and booked an appointment to have someone come to my job and install it the mechanic that came out was Tien, he installed the parts that I had ordered online but told me that the part was bent somewhere and wasn’t working properly so I thought to myself here we go, I just wasted my money by having him come out and he can’t install it, but to my surprise, Tien was able to use spacers or something like that so that the window would work properly, he definitely did not have to do that by me ordering the part on my own, he went over and beyond to make sure my window was able to roll up and down and I could close my door, so since I had such a good experience when I received the recommendation via email regarding other service I should have done, and the price that it would cost, and the estimate was very reasonable I booked another appointment, that appointment was yesterday march 18th and that service was also excellent, so I think I’ve found my new mechanic.

I am completely satisfied with the service Patrick provided. He was very professional and listened to all of my concerns (unlike the dealer service department). Patrick and YourMechanic communicated every step of the way. I would recommend Patrick to anyone needing service on their vehicle.

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.
