Joshua found the source of the problem almost immediately upon doing his Preliminary Inspection ( it was NOT what I called him for). He showed up for the appointment we made for the repair and I was impressed by his professionalism. He had all his equipment and parts in order and did exactly what he promised in the time we allotted. He answered all my questions and I could tell he was very knowledgeable and was also conscientious about his methodology: he cleaned all the parts, he solved two more problems he noted as he worked, and when he was done, my truck was HAPPY and he didn't even leave a drop of oil on the ground, or a dirty fingerprint on the paint! Joshua is a credit to all mechanics everywhere. I HIGHLY recommend the services of YOURMECHANIC.COM.

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.
