Not 2nd Gen but uncannily I have the same intermittent misfire on my 1st Gen. I have narrowed it down to the rear right cylinder, when I take the lead off the plug, problem goes away.
I have,
Replaced the plug>no change
Swapped out plug caps to narrow out the plug cap>no change
What should I do next? Could it be the coil? How do I check it or as RSTDdog suggests, should I be looking for a fuel problem??
Any help would be greatly appreciated!!!
