A+ mechanic. My 2011 BMW 535i required a special extra thin spark plug socket so Chris couldn't swap out the spark plugs for me on the first visit. So he rescheduled me for a different day so he could order the special sockets needed to work on my car. He is very knowledgeable and got the plugs installed in a timely fashion for the second visit. Would definitely recommend him!

Although my car's system status indicated that the brake pads had to be replaced, Michael discovered that the sensor wire was severed and only needed it to be replaced. Saved me a few bucks. He could have replaced the pads, but chose to do the right thing. Good job Michael!

Carols was helpful, honest and pleasure to work with. He gave me a hint of what to do with my car from this point because it does need some work. I was happy because he gave me a couple pointers on how to get my car fixed with paying a lot for it.

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.
