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?

 

Suggestions?

 

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.

 

Any other suggestions?

 

My a/f gauge keeps fouling out my o2 sensors

 

Air/Fuel ratio gauges can foul out o2 sensors?

 

do any of you have a how to guide on installing gauges? i have searched the forum but havnt found much

 

Yeah I wired in a a/f gauge and within 30 min I threw a code on the u2 I wired it on.
