i recently installed an auto meter A/F gauge and i think theres a big problem cuz all it des is sweep back and forth very fast while driving . Although sometimes entertaining when it seems as though it goes ot the beat of the music, it isnt doing its job. anythoughts on what might being doing this? wrong wire on ECU?

 

Thats all its going to do.

Narrowband air/fuel gauges are nothing more than pretty lights. It is of no help as far as information goes.

Invest in a wideband air/fuel meter if you want something that will give you some useful information.

 

what he said.. I had a narrow band....useless....i'm getting a wide band so i can actually use it.
