As usual,Josh was extremely knowledgeable, articulate, and works quickly, despite my presence asking questions....:-)...This comment is based on numerous visits since 12/15...sadly because aging Euromobiles need lots of TLC...but that's not Josh's problem.....

I had an excellent experience with Robert the mechanic. Every thing went as described. He was efficient, knowledgeable, and industrious. No time was wasted and all was completed as scheduled. He communicated well and explained everything he was doing. He thoroughly checked the entire car and found a leaking gasket to be repaired in a follow-up session. I would be pleased to recommend Robert and YourMechanic to one and all. Joe Papa, San jose

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.
