Jason went far and beyond what I could have expected! Do to an incorrectly assigned time for completion in the job I needed done, Jason did far more work then he knew was coming. I needed my PCV hose changed, and low and behold, my Mazda required the removal of the headers to get to the PCV hose. Without question, Jason handled his business and got it done. On top of that, he replaced my brake discs and pads, and on a request after he arrived, he went to the auto parts store and bought and replaced one of my headlights for me. Jason ended up working for 8 hours to get the job done. Then, after there was an issue with my power steering making noise after he worked on the car, he responded quickly and came out to my work to figure out and fix the issue. Jason did a great job, and I definitely recommend him to anyone needing work done. He will go above and beyond.

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.
