A bad Oxygen Sensor will cause your cars engine to run rich on the fuel mixture which can increase your fuel consumption and lower your gas mileage.

When your oxygen sensor is bad your car may also run rough, hesitate on acceleration, engine stalling and rough idling.

Your check engine light may also suddenly start flashing.

A bad oxygen sensor will also cause your vehicle to fail an emission test.
