I have an older Mercedes 600SL and was somewhat concerned about using some one other than a dealer, but my fears were put to rest after my initial conversation with Steve. Steve was on time, knowledgeable, had all of the required tools. diagnose the problem and gave me a stalemate of cost for the repair. He did not try to over sale me on something I didn't need. He made the repairs made sure that everything was correct and assured me that if I needed anything more he was just a phone call awaly. Steve called me the next day just to check that the repair was good.

Dave arrived on-time. In replacing the front brake pads, he was highly efficient (fast) in completing the job. He shown me the brake pad senor indicating there is only 1, not a pair of them. That fact saved me a few dollars on the bills.

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.
