I'm Rich, then Lean, Help me out please, motor prob, or guage, or install?? Options

[creis]

I just put in 2 After market guages in my car, a volt one, and air/fuel, one on the window pillar. they look great, and my volt one works good, funny to watch it bounce all over the place, when the bass is up. anyway, my air/fuel guage is wired up right, or so i think, but when i pluged it up, and turned it on, it went all the way to rich, as far as it can go, and stayed there, no movement, now, a day later, its all the way to lean. and dose not budge, I have no idea what is going on, is it installed rong, or should i stay away from getting my imitions checked.

Please someone help me out.
