Rocco came to my home to check out my car since it would not start. I did not want to go through the hassle of having to tow it to a repair shop and wait around. I had a problem with my starter. With repairs like this you would think you'd have to go to a repair shop but I'm relieved I was able to have it fixed at my home from someone professional. He came and checked out my problem (which took less than an hour), provided an estimate along with how much time/labor would be involved and the next day came and made the repair. And I was able to save time without waiting around for other customers and cars ahead of mine like at a shop. I'd definitely use the service and call him again in the future :)

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.
