Jose

We will definitely use Jose by request in the future. He was very professional and efficient. He came from beaverton and changed my oil in my GMC truck and serviced my Differential, then travelled all the way back to beaverton again, then came back and changed my wife's Volvo XC90 oil within three hours. Then they told him he had another oil change back in beaverton AGAIN!!! He never complained. I would've told them to "kiss my a--"! THANK YOU JOSE.

Enrique

Enrique was very friendly, professional, and positive! He provided excellent customer service, like a doctor with the ideal bedside manner. Examples of this are that he patiently listened to me, showed me the issues my car was having (which has happened maybe only once or twice in the 25 years I've been driving), and he explained to me the way it would affect the vehicle. He was the best service adviser and mechanic I've ever had.

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.
