Ben

I tried another mobile mechanic service, and that mechanic told me that I had a blown head gasket, and the repairs would run $1,300! Within 20 minutes Ben found the problem and had my vehicle running...all it was is the rotor button screw had come loose and the rotor was not engaging. So $70 vs $1300! Needless to say, I'm a VERY happy camper! So many people today will try to take advantage of seniors, especially if they are on disability. But the honesty and integrity of this company is par excel lance! I would encourage anyone to use this service, instead of going to a shop or trusting shady backyard mechanics!

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.
