TJ

TJ arrived at our house exactly on time and replaced an axle/CV shaft assembly on my GMC Envoy. His work is excellent, and he is very knowledgeable, detail-oriented, and easy to talk with. He answered all our questions perfectly, and made sure we understood his answers. We had no worries at all about his work. Due to physical limitations, it is difficult for us to go to a garage - We are very thankful that he is able to come to our house and work on our vehicles. It's like having a good friend who is an excellent mechanic, too! We always look for TJ when we need to have automotive work done, and we highly recommend him to all! Thank you TJ! :)

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.
