I made an appt. for Tien to come by and replace the fuel pump for my no start diagnosed by him through the inspection I had a few weeks earlier. Tien got to work on the car immediately on arrival. As in many if not all jobs, it turned out to be a more complicated than expected. In the process of changing the fuel pump, he discovered that the new fuel pump was slightly different than the one being replaced and the wiring would need to be adjusted somehow to be able to use the new one. It was amazing to see as he used his knowlege and experience to make the necessary adjustments to make the part work! He could have taken the "shortcut way" which a lot of mechanics would have done. When he removed the old fuel pump, it seems that only the fuel hose part was damaged beyond repair, but the rest of the unit was intact and probably still working. He could have maybe just changed the hose part and left the rest of the old unit as is, but decided to replace the whole unit if he could, pending the wiring adjustment mentioned above. Thanks Tien for a great job highly recommend you to everyone!

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.
