If the oxygen sensor is going bad the fuel-delivery and fuel-combustion systems will be thrown off. If a bad oxygen sensor disrupts the air to fuel ratio mixture or too much. Recognizing The Symptoms Of Bad O2 Sensor The O2 sensor determines whether the mixture of fuel and air is too rich having deficient oxygen or having too much oxygen.

In case of any condition it sends the signal to the engine control unit so it can be adjusted to normal. Used Oxygen Sensor O2 Comparison So after all your testing you should know whether the O2 oxygen sensor is bad. Or if something else is the problem.
