Scheduled an appointment for spark plugs and wire replacement and blown away again by this companies service! Just the best mechanics to deal with out there. I had Steven Laramee come out for the service which he did quickly and efficiently. I also told him my problem about my oil pan drain plug being stripped and I couldn't get it off. Not only did he get it off, he did my oil change for me with the supplies I already had! He did this as a favor and its stuff like this that goes a long way when it comes to customer service. That is amazing considering the way other mechanic shops would have treated this! Just the best in town for auto repair and they come to you at the office or home! Thanks so much Steven!

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.
