Default Air/Fuel Gauge Problem

I have an Autometer Air/Fuel Ratio gauge that was installed 3 years ago. Recently the gauge stopped sweeping/reading; I realized that the O2 sensors crapped out. I replaced the O2 sensors (front) and now the gauge doesn't "sweep" like it used to, where it would sweep and then state whether the air/fuel was lean, stoich, rich. Could the gauge be going bad?

A/F gauge should have one sensor per gauge, unless you got two gauges for each sensor. not sure what u mean by front sensor..... what is th setup actually?

I have one air fuel gauge hooked up only to the front driver side O2 sensor. I had it reading only the passenger side for a while and then it stopped reading, so I moved it over to the driver side bank.
