Where did you place the sensors and is it a wide band type unit.
The cheap types are only arcurate at or around 14.7 otherwise you see what your seeing on the guage.

the sensor are on the mani but i tapped the signal wire to both of the sensors and all im getting is a wide range back and forth signal, i thought the signal was a steady reading not a fluctuating signal..i just wanna know if this is right.. dose anyone else have this prob...

The oem oxygen sensor is not very accurate. You need a wide band sensor. It has a more linear voltage output. Your gauge is useless untill you get the wideband sensor. Even when you have the wb sensor the gauge is not really useful for tuning. It will just let you know if something is wrong.
