I have a 1994 pontiac sunbird, 4 cylinder, 2 litre coupe, I think the oxygen sensor is gone but I don't know where it is located. Could you please tell me where it is? I am a woman so please put it in terms I can understand.
Thank You very much

Do you have a check engine light? Not to fast on the O2 sensor might be something else causing it-

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it
