This was my first time using a at home service for my car , after reading the comments from other customers I decided to give it a try , and oh my gosh I was totally shocked by the professionalism that Rodney provided he showed up early which I was fine with cause I am a tickler for being on time and on time he was , so that was a big check mark , professionally dressed with company logo uniform . Not only did he find out the problem with my car but also did a inspection of the entire car , let me know that my tires were low and recommended that as soon as i get it running go and get them inflated and told me what pressure for front and the rear . So yes I was very happy with Rodney and the service he provided and the overall attention of the company putting customers first . Looking forward to seeing Rodney next week for the repairs .

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.
