can anyone identify these codes?

Yes, there's definitely a noticeable seat of the pants feeling in mine, too, when I run on the rich side. I notice it everytime I reset my computer. Eventually it goes away when the computer adapts, though.

I'm working on a way to remedy this. It involves using a potentiometer on the o2 sensors to tune out some voltage. I'd like my solution to help people who want to run leaner, too, so it may involve some amplifiers. Any advice from an electrical engineer would be greatly appreciated.

You need an analog voltmeter with at least 10 Megaohms of input impedance. A digital voltmeter will only give you average voltage. An oscilliscope would probably be pretty cool. I wonder if it's possible to pick one up cheap somewhere.
