Tried this service for the first time. My problem - sometimes my auto's engine would race, the tachometer would be very high but my car would start slowing down, as if it had lost power, but after a short time the normal power and speed would be working right again. Very scary when you are driving on the highway at 70 mph. then this happens, and you seem to be coasting down to 30 mph. before your car starts to engage properly again. Pete Hambly to the rescue. I explained to Pete how my car was acting, and he surmised what the problem was very quickly before he even hooked up the code reader to my auto. After reading the code and doing a few tests with his instruments to verify his prognosis, he solved the problem. He looked at my part and found a faulty connector sensor. He temporally fixed the problem until the part I need is found. Pete was friendly, informative, professional, very knowledgeable, courteous, and proficient. He was clean cut, well mannered, and made you feel at ease. Pete gave me the impression he loved his work and it was more than just a job to be done. I am very happy I used "Your Mechanic" services and got Pete as my service technician. My cost was lower than if I had taken it somewhere else and more personable. Communicating directly with my technician instead of a clerk behind a desk, that writes up a work order for the mechanic to read, solved my problem faster and with more precision. I will definitely use Your Mechanics services in the future and definitely ask for Pete again. Thank You very much Pete for a pleasant stressless hour.

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.
