O2 sensor, wide band or narrow band????

[CoolColombian]

Does any one knows if our cars have a wide band O2 sensor or a narrow band O2? Thinking to buy a A/F gauge but don\\\'t know if i\\\'m gonna need to buy the O2 sensor or if the stock one will work with the gauge.

Our 2 HO2S sensors should be wideband since our PCM increases or decreases the fuel injection amount based on voltage readings from these things (smart ass CAN-BUS PCM)
