Platinum plugs - resisting fouling?

[Christopher Hoffman <imperial67@xxxxxxxxxxxxx>]

James,

I've found that none of my older Mopars (and that's 1993 and older) likes
platinum plugs, even the Autolites. A rough idle was the most noticeable
undesirable effect. And with standard Autolite plugs so cheap (and all but
one so easy to replace), the result seems far more satisfactory overall with
the non-platinum plugs, from my experience.
