Peter

Before booking any services with your mechanic, I was highly doubting whether to or not. I decided to give it a shot with the inspection. The mechanic that worked with me, Peter, took all doubts away. He arrived even early to the appointment. He was very professional, and extremely helpful. The mechanic went above and beyond expectations. Had very great customer service skills, easy to talk to and explained things thoroughly about problems with the car that needed attention. He allowed me to stress a tad less about my problem, knowing he had it fully under control.

My car was running rough and shaking when idle, so I booked an appointment for an inspection. My mechanic was Jose Guzman. He did an inspection, and he found the car has eccentric shaft sensor and camshaft Position Sensor problems in just less than 10 minutes. I was impressed by his knowledge and experience about cars. He did a great job today.

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.
