    Finally got a wideband. Take a look, slow learner. :)

    Finally got a wideband. I've been working on the fuel trims, but I that was before the wideband. Should I start over, or is it salvageable. After seeing how much the wideband goes back and forth, it makes me wander if I have some kind of fuel issue. Thanks for helping out. I greatly appreciate it.

    I looked at the log. By letting the log run all the way thru while observing the histogram for the wideband's measured AFR, I can see that it shows the ratios are near stoich until the higher RPM's, where it goes quite rich (10.5:1).
    I would look at why that is. PE Equiv ratio?
