Air/Fuel Ratio gauge

[TEXSN95]

At idle does your gauge bounce around? When I start it, it's lean for a bit, then as the rpms go down a bit when it's idling, I dont get a reading anymore until I drive. We spliced into the 2 EEC wires for the 02s, and ran them to a 3 way toggle. But when I switch from the left to right, the readings look exactly the same, like it isn't reading 2 different sensors. So I dunno what the hell is going on.
