Patrick

Patrick did a great job he is a very well qualified mechanic. And he is most pleasant to work with very courteous and helpful. We had one oxygen sensor that the GM company sent us that was the wrong plug and part. Patrick noticed it right way and I had to reschedule him to come back when I receive the replacement.

Jose was very professional, was on time (actually a bit earlier than expected which was just fine for me) and did the job in a timely fashion. There was a mix up with the part but he went out and was able to get the correct one, at no extra charge for me, and he even made sure that everything was working afterwards. Did a great job and would definitely recommend to friends and family.

Brikk

Despite the part delay, rescheduled appointment, obnoxious heat and a completely dead battery (none of which was at the fault of Brikk) Brikk was able to power through and get me and my G8 back on the street. Brikk gave me some oil lubricating tips for my over 150,000 mile ride. He trusted the information I provided about my alternator issues and was able to complete the job without any glitches as far as I know. 1st experience already referring... Thanks a bunch.

There's times when you expect and there's times you're surprised. Zack displayed exceptional customer service, superb execution, and great patience. The key turned and success. In addition, he completed a 3 hr task in advance with precision. Finally, I had lost something important in some grass vines/dirt and he offered to help me find the missing item. Now what mechanic does that? I'll tell you, zack, your best mechanic!

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.
