Air Fuel Gauge not working

[Corey]

I've been trying to figure out this problem for a while and i havent seemed to figute it out yet. Alright so my air fuel gauge doesnt light up or anything. But at night sometimes i will see a little red light come on on the left side of the gauge every time i step on the gas. Any ideas?

airfuel gauges are shitty its pretty much just a light show throw it out and get a wideband

Narrow band gauges arnt worth a shit anyway even when working.

If it's a red light showing on your left side of the gauge, it's telling you your car is running lean. Ka-Boom.

nissan O2 s are narrow band, that thing isn't doing shit

^^ like he said- buy a wideband
