O2 sensor XFI

[Fuelie Nova]

Is there a application I can use for a O2 sensor on my XFI setup? I intermittently log an O2 error and would like to be able to go to a NAPA to pickup a new one.
I have had these intermittent errors since installing a new one that says NTK but it was half price on the internet... sealed in a NTK box. Maybe it's junk??

Just log all your o2 voltages on the screen and it will go red if there is something funny going on.

IS the XFI not showing any fault codes? For WBo2?
