I also have a tale of woe to share. Finally got to changing my spark plugs. Got to the second plug, on the cylinder that I suspect is misfiring, and the ignition coil is missing the top rubber seal. Somebody pooped it up with some gooey crap. Obviously I don't want to put it back in without a seal but I doubt I can make a decent seal with silicone unless I "permanently" silicone it in there, which isn't going to happen. Set of 4 coils on eBay for about $50 shipped. I'll call Honda to see if by some miracle they're only $15 new.
*edit*, what a shock, $60 new for one!
