i don't know if they were the wrong plugs:
i have them and they are
NGK
R
BPR6EY
11
the fsm says to use:
NGK
BPR6ES - 11
i don't know whether the Y vs. S is important (because i got "champion RN9YC?"
(the box is in the car) however these are different in the last number but the
place's (where i got them) catalogue says there are fine for that auto. (should
be RN9YC4)
the former plugs are charred.
what was changed: there was <apparently> an exhaust leak which was fixed
(replacement)
and an emissions treatment (something for the oil; engine and gas) it had an oil
change
then it failed nox (>2000?) and was "readjusted" -- the place said that it had
to be reset.
it apparently passed after this

it became black last summer on several occasions (xs rich exhaust) so i don't
think that it is worse -- difficult to tell

hardly any -- uses VERY little oil

this is why i would really like to be informed since i have no idea whether

A quick Google search turned up several places that say that the Y has a
V-groove around the electrode and the S does not. This particular hit:
http://www.geocities.com/motorcity/downs/3837/sprkplug.html claims that
the V-groove improves performance. I don't know if the Champions have
the groove or not (I'm confused from your post as to whether you
currently have the NGK ...Y or the Champions), but it doesn't sound like
either of the NGK or equiv. Champion plugs would be a catastrophic
mistake being that apparently the groove is the only difference between
the 'Y' and the 'S'.

thanks for the information
the champion RN9YC are in the car now.
the fsm recommends champion RN9YC4 -- but apparently that (the '4') makes no difference
(i assume b/c they don't exist anymore)
i found the actual car on an auto parts Web site and either the NGK BPR6EY (v-power) OR
NGK BPR6ES (standard) or the champion (without the 4 at the end) are recommended.
i don't think it is the spark plugs.
thanks very much for the link
sincerely

The "4" just indicates the packaging... It means there are 4 of them in
the package. Meaningless...
