Tien

I got a text saying Tien was on his way, so the five minutes he was late due to traffic and a part pick up didn't bother me at all. He did exactly the service I requested, plus an overview of my newly purchased used vehicle, and didn't try to sell me a bunch of extra services. I was given a quote of $171 when I made the appointment, and I was charged exactly $171 when the service was completed. Pep Boys gave me an estimate for the same service of c "$325, minimum" just last week! Tien did find an additional issue I need to take a look at, and gave me a reasonable explanation with pictures showing the area that needed attention. i'll be booking the service for that in a couple weeks. The ease of making an appointment and paying online, the convenience of them coming to me, the integrity of their quote being the actual price, and the thorough service provided will keep me coming back (and recommending to my friends) for all my maintenance and service needs!

Robert

Very satisfied. Robert diagnosed the problem correctly and fixed it on the spot. He was courteous and helpful, and explained clearly what he was going to do, and why. He also gave me an estimate for some necessary further work, and showed me why that also needs to be done eventually. He is obviously a competent mechanic and understands the electronics involved. I would be glad to work with him again.

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.
