few air fuel gauge questions

[greeneclipse]

i have an autometer phantom air/fuel gauge, and i dont know if i am reading it properly....


whenever im cruising around, the gauge cycles up and down like its supposed to, but sometimes if a rev freely the guage will light up in sync with the rpms. like if i revved it hard it would go all the way rich and then fall back as the rpms go down, and if i rev to 3-4 it goes 3/4 of the way and falls back. Is this normal?

also, whenver i floor it it goes all the way rich. does this mean im running rich, or is the gauge screwed up?


sorry if its long, and thank you in advance.

You're reading it fine. It doesn't read the O2 sensor too well. Actually, that's not really the case, it's more like O2 sensors don't respond very well.

A/F gauges are best thought of as gauge-pod cavity fillers.

The o2 voltage should jump all over the place.Don't even waste your money on another one.
