I knew I remembered this from somewhere... the plugs that came in my
coup-e engine ran for about 45k miles (!) until one day all of a sudden
I was getting backfiring, bucking & power dropouts.

looked at the ole spreadsheet for things that were overdue and those
really long lived Bosch plats got replaced by some new ones.  problem
solved.

I do tend to think "bucking" in general is more likely to be ignition
than fuel, but just genereally.

yeah, how bright that little spark is really matters.  fat whitish blue
and hot, nice.  piddly, yellow, can't see unless its real dark out, is
not a good spark...
