That's about where I'm at now as well. I have a spare igniter and P/U coil that I want to try for nits-n-giggles, but being wet/cold, not sure when I'll have an opportunity to do that. If I do, I'm still going to do one at a time so I can eliminate either one or both as possible causes.
Did you ever crack your alternator cover to check the gap on the P/U coil?
I'm just curious if either running Iridium plugs or simply indexing the plugs wouldn't take care of the occasional hiccup or stumble at dead stop idle.
