He called and asked if he could come early, which was perfect! When he arrived, he was so personable and very friendly. Great conversation, which it made it that much more comfortable. He was very patient with my car and let me know exactly what was wrong, verbally and physically. I will be seeing him again tomorrow to get my car worked on and I am that much more comfortable with that happening. I work Mon-Friday an hour and half away from home, so this idea was perfect! Thank you so much! Will be using from now on!

Great experience. All I had to do is to give my keys to Shaun and continue with work (I was at the office). It took about an hour to get the oil and filter changed. It was also nice to get a report on my car after the inspection, I didn't know that is included!

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.
