i thought the obd0 o2 sensor was the blue wire, im not positive. just run a wire directly into the engine bay and tap onto the o2 sensor. with those a/f guages the lights should be all over the place unless your at WOT,sounds like your wired it wrong.

 

They're completely inaccurate anyways

Depending on what source you use to give them power, will effect how they read. I connected mine to wires in the dash panel, and when ever I turn on my lights there is a voltage drop to the A/F gauge so it starts reading less rich its ------- pathetic

 

The BOV is constantly adjusting itself based on the pressure it feels, correct?

I noticed in this new one (I got an RFL now) I can watch the valve move up and down inside of it at idle. I have tried adjusting the spring pressure, but irregardless there is still "flex" in there. I am pretty sure its a mechanical and not a electrical thing, because I can turn the engine off and then on real quick (reset the ECU) and it will have no effect on it.
