I've been working on my Cruiser electrical. When I bought it the LEAN-STOICH-RICH gauge wasn't working at all. I traced the wires finally and noticed that it draws power through the same source that the front spots do, replaced that fuse and I'm back in business with both. The problem is that the gauge reads all over the place. When I start the engine, the gauge starts up and indicates a very RICH condition. As I drive around the neighborhood, it mostly bounces between the RICH and STOICH area. If I give it gas very gradually, it seems to stay pretty stable, but if I give it a bit more, it dips into the LEAN area for a sec and then comes back up. Is it supposed to bounce like that? I haven't tried romping the gas at all for fear of the unknown, but from what I understand from Christo, it doesn't take much to burn one of these things up. It also died on me once when I abruptly let off the gas. Does this indicate anything? Now I'll mention two things: 1. The L-S-R gauge has 3 thin gauge wires, two for power, and the Purple wire for the voltage signal from the Diag Port. (I'm only guessing this from following the wires around.) But in following them I noticed that the Purple wire had been spliced with another wire of considerably thicker gauge to reach the Diag box. Is this a problem? Could this be adding to my woes? 2. My cruiser is also equipped with an APEXi Super Air Flow Converter, does anyone else run one of these things, or know anything about them? I read a 45 page PDF on it last night and from what I can tell, it's a "middle-man" that sits between the air flow signal and the ECU. You can then use it to "trick" the ECU into providing more fuel at given RPMs and throttle conditions. Not sure if I'm right in this or not, but that's what I gathered. Could this be causing/adding to my problems? Any ideas? I consider myself pretty good with electrical systems, and capable in the mechanical areas, but this whole fuel mixture/air flow thing is just not my forte. Just thought I'd throw it out there to see what y'all thought. Thanks.
