Correct spark plug?

[PeterBergin at aol.com]

Yea, good to see some good old list controversy again!  I ordered the correct 
plugs and wires from Blau today.  My miss (midrange bucking) seems to go away 
after 30 minuets of driving.  Probably the original wires going (been damp in 
the Minnesota mornings lately).  I do have over 60k on the plugs.  When I 
replaced the last set, the electrodes looked good, however the porcelain was 
cracked on number one, thus creating bucking under load.  I spent a ton of time 
and some cash last time looking at all the other alternatives and should have 
started with the simplest!

If this doesn't solve it I will be back on in a few days looking for advice 
on plan B.

Thank to all!
