When an oxygen sensor is bad or going bad you might notice a drop in your fuel mileage and even rough idle.

The Oxygen sensor is there to measure and control the fuel/air mixture, engine combustion intervals and even the engine timing.

It's important to have a properly working oxygen sensor to have a properly running and working engine.
