I've searched online and some say it's from mis-wiring, or bad o2 sensor...

I have autometer gauges.

Ever since I got my car that came with blower and guages hooked up, the A/F will read on the very highest stoic (rich) reading, and at night when my headlights are on, sometimes I see the meter go from lean to stoic as if it's glitching. I say glitching because it bounces left to right sort of like how some newer car's RPM reading will redline then bounce back to idle when starting for a cool effect.

Gauge runs from 8 to 4 o clock and is stuck on 4 o clock

Anyone had this happen before? I'm wondering if my guage is dead.

If its full rich usually means the o2 sensor is bad.

Do you have a scanner/tuner to see the voltages that you're O2's are putting out. That will at least tell you if they are functioning correctly, I had an O2 pop the other day and it was reading 1.25 volts when the O2's should be only reading between .1 and .9 volts.

Thanks guys.

No scanner or tuner but I guess I could try autozone/Oreilleys and get a free scan... but wonder if it's still free without a check engine light. I'll call them up tomorrow

Being supercharged I really need to address this guage or o2 issue

Just dont get in a race with the Farm Truck till its fixed! LOL

There is a video on youtube that shows you how to check your sensors with a can of brake cleaner.

Brake cleaner, tb/carb cleaner, spray a little in a vacuum line, with the tuner/obd2 hooked up and watch the 02 voltage if it spikes to .99 then you know the sensor is operating correctly.
