Dear list gurus [and others, like BenT, semi gurus]

I had reported that my van started missing under load on a trip to Southern
California last week.  then progressed to missing under less and less load,
now misses all the time.

I tried a new fuel filter [the old one was dirty] and a new coil [the old
one was dirty, don't know how well it worked], no help.

My brother suggested bad plug wires.  I didn't think they'd go bad in that
fashion but I went out tonight and looked at the engine running in the dark.
Sure enough small sparks where the driver side plug wire and coil wire go by
the A/C compressor.

Question:  What plug wires should I get, and where best to get them?  I'm
off to operate a tri sport camp at Tahoe August 4 so I need them at least a
couple of days before then [anyone want to come to Tahoe to run, bike, or
swim, or my personal favorite, nap.  List members given a special discount:

Thanks for listening.
