Honorio

Honorio took the job on his day off after the 1st mechanic could not make the scheduled Sunday morning appiontment. He arrived on time and conducted a pre inspection of the car as well as the struts I purchased. He took his time replacing both struts and thorough going the prcess of replacing both front end struts and then drove the car to insure the replacement struts were operating properly. Overall, a very good mechanic which I would happily use again in the future.

That is the first time I tried your mechanic and the experience was positive. The mechanic arrived on time. While he was working on the car I was able to do my work. So I saved around 2 hours that I can now spend with my family and friends.

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.
