I didn't realize he had one going on there too. Funny you mention lean fuel mixture, I was thinking the same earlier this morning, top of the idle circuit - put a couple wires in the IABs and see if that solves it. Then decided nah, the description of the miss didn't seem to quite fit. For all we know the plugs so carbon covered thats the immediated cause. Tough to fully get a feel of the issue(s) without being there.
