I hooked up an Autometer A/F gauge today, and either the gauge is screwed up or I tapped the wrong wire on the ECU, or it's normal and I don't realize it. When I started the car after hooking it up, it seemed fine, but when I drove the car later, the gauge was going nuts! It was going from lean to stoich to rich rapidly! It was also not showing anything at times. There doesn't seem to be any sort of pattern, although it did SEEM to be somewhat related to the rpms. Can anyone tell me how it should be working or offer any suggestions? Thanks!
