Josh is a great guy and is very professional and boy is he ever thorough. He called me that morning and told me he had a cancellation and asked if he could come by earlier. I was happy to have it done earlier. He called again when he was nearby and said he'd be here in 5 mins. He's friendly and nice as can be. He knows what he is doing and explained it all to me in terms I could understand and then quickly got to work. After he finished, he told me about the front brakes being worn and recommended replacing them soon. He didn't pressure me to have this work done, just that they should be sooner rather than later. Based on that recommendation and the fact that I am starting to hear something when I step on the brake....so, I have made an appointment to have the brakes replaced and I am glad that I was able to book Joshua. Thank you!

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.
