Very informative. He advised me on what I need to do in the future for not just my Buick but for my Toyota truck as well. Our problem with the Buick was the vacuum hose had come loose.

My appointment was scheduled for 10:00 a.m. Kyle called to say he would be about 25 minutes late. He arrived when he said he would. He seemed knowledgeable and was polite and friendly. He quickly came to his conclusion that my old Buick was done and I should look to buy another vehicle. A little too quickly for my liking, but he was not trying to sell me parts or services I did not need. He gave me good advice on how to financially maximize what's left of my old car. My only criticism and it's a small one, is that he did not seem interested in hearing my opinions or comments about what I had done to or replaced on the car. He seemed confident that my vehicle was beyond repair and moving on was my best option. I would use YourMechanic Services Inc. again.

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.
