Tom

Tom provided excellent service. He inspected the car and wanted to make sure that the battery was good before going any further. He had a generator and a charger in his van which he used for about 30 minutes and tried to start the car a few times. The charger showed the voltage fluctuating between 15V and 13V which he said is not supposed to happen if the battery is good and can take charge. He suspected that the battery is sulfated and needs to be replaced. Since the battery is Interstate and less than a year old and still under warranty he advised getting it replaced first before looking at other things. My first experience with YourMechanic and with Tom has been very positive and I won't hesitate in recommending your services to my friends and colleagues when they have any auto issues.

Maxwell

Maxwell got to the house before the scheduled time and quickly got to work. He did an inspection on the car in which he did a routine inspection which took about 30 minutes. After he called and said it was done he went over what he believed needed replacing. In the end he was extremely nice and professional. I will definitely be having Max continue the work on mu car 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.
