Clarissa was wonderful! She is very friendly, knowledgeable and honest. If I could give her 10 stars I would. I usually work on my on car so I have an idea of how much work goes into repairs. I am the type of person who laughed at other mechanics and walked away when they tried to sell me a service I didn't need or for a ridiculous price. From the start she responded very quickly to my messages answering my questions and even added a last minute service the day before she was scheduled to come to my home. I had an old car being held together by rust and prayers. I had some parts and she immediately called to remove the cost from my bill. She showed up on time, listen to what I had to say and then looked over my car. She pointed out the issues and helped me weigh the pros and cons of how to handle the situation. I would highly suggest her to anyone who wants a mechanic they can trust!

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.
