    AFX wideband

    I have AFX wide band and went out to do some logging and noticed that the A/F is off on scanning then my wide band. What would cause this and how to fix ? When scanning it is stuck around 10.3 ish. No matter what rpm and full, partial or idling all the same.

    whats the screen of the AFX say? If it matches, could it be a bad sensor? I assume the motor runs fine?
