more Help!!, Engine Running Lean Options

[D-Man]

Okay, so i installed an AFR gauge this weekend, and everything seemed to be in working order. Until i got on the road for work this morning. After my engine warms a bit, I fall lean during idle (red light); and WAY lean when i begin driving (green light), after a second or two (not sure yet if it's related to RPM or speed) it'll return back to stoich, and stay there until i come to a COMPLETE stop and will gradually dip back down to lean. at the worst of it, it sits about 2 points into lean.

WTF could be the reason for that?

Nope, that one is slain. Turns out the alarm had nothing to do with it, It was a striped wire elsewhere. I'm thinking i'll check that set of wires for other imperfections, but i wanted to know what could cause this, that way i can track it down on the wiring diagrams, and know exactly what wire is bad, or know what mechanical error is wrong. W/E the case.

the AFR is:
POS(+) cig&radio fuse
NEG(-) BATT
SENSOR at the sensor
and the other wire didn't do anything but dim the gauge.

Also, Negitive is on the BATT because when i grounded it, The car died. WTF?

But when you went to the battery it acted right? Where the fcuk did you ground it to? I still have all my old wires for that gauge setup so we could always test things that way [Yeah I didn't use that dimmer wire either - leave that one alone]

First i had just tested it under the hood to figure out the wiring, everything was good, so i installed it, and grounded it under the fuse panel, where the bottom plastic screws to. Then when the engine started struggling, and AFRG was showing me a lean reading I went back to under the hood (test position) and everything was fine agin. So i put the neg. to a bolt near the Driver headlight, and the engine died right away. So it seemed that unless the NEG was on the battery, than the engine was going to fcuk up. I figured maybe there was too much ground-noise in the ground for the gauge, and maybe it was bleeding into the sensor and causing some unwanted reactions.
