On time to the minute. Got my car that had been sitting for a while starting perfectly at an amount that was less than the quote, and gave me a heads up on what things I should fix up soon and what could wait. He even reset the time on the car clock after replacing the battery!

Tyrone is very experienced mechanic providing excellent service. Although it was Sunday and I didn't mind to wait as needed Tyrone arrived on time and started to work on my two cars. He serviced them promptly, explained everything, recommended to change one part in the near future, and addressed all my concerns. I guess, I am done with dealerships now. Tyrone is my mechanic!

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.
