I was very impressed with the professional manner in which Joshua did the diagnostic test, and clearly explained to me the problem, and when he would return to install the needed part. He also gave me some helpful preventive maintenance tips to prolong the life and value of my car. I have decided to have Joshua service my automobile as needed annually. I plan to share the cards he gave me with my man friends. I never dreamed that I would ever meet a mechanic, and leave with a smile on my face. his personal mobile phone.

Awesome service on my brake pad replacement! He showed me I had about 30% wear left on my old brake pads, but glad I did the service now and not wait until the last minute. Took the car for a spin before he left and the brakes feel great! Thanks Alfredo! I'll be using this service again.

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.
