Could not have asked for a better mechanic. Ben arrived 15 minutes before appt. (what a wonderful surprise), got to work on my car, was finished timely, cleaned up the door. He was polite, cheerful and personable. It was such an unusual experience to have a mechanic who fixed your car and didn't try to "sell" you more that was needed. Usually my husband has to first meet the mechanic to ask for an estimate because we found out that it's always higher when I ask for it! I will recommend Ben to my friends. By the way, Ben was recommend to me by a friend of the family Cedric Senter. (he should get the $20 you offer for recommending Yourmechanic)

Had a coolant leak. Needed an engine gasket and thermostat replaced. Also needed a flush of the coolant system and oil change. It was a very long job and Danny was dedicated to getting it done. He also gave me other automotive advice and answered all of my questions thoroughly. The car is no longer overheating or leaking. He did a great job. I would definitely use this service 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.
