I am getting this post as a 're' in a cross post from somewhere....

I don't understand how a tune up fixed a 'short' in the wires? Was a
plug wire arcing out to the head?

When my 86 CJ7 starts missing, I check plug wires. The last time, the
wire to #1 plug was loose. Pushed it back on tight and away I went.

Then I check the distributor cap. They are open to the air and get dirt
inside them easily through the vacuum advance linkage hole. Then they
arc out.

There also is a bad bunch of cap and rotor combinations out there! The
rotor is too short for the cap making too big a gap so they start arcing
out after not many miles. This causes a miss. The arcing will be
visible when you open up the cap and look inside with a bright light for
carbon tracks and built up crud on the contacts.

If all is fine there, then I change the gas filter. You have to be
careful to get the gas filter in right side up. It has 2 outlets, the
center one goes to the carb and the 'top' one goes to the return line.
If the return line isn't at the top, gas can syphon back to the gas tank
when it sits causing hard cold starts and misses when the filter starts
to get old.

Then I check the coil connection. That crappy Ford coil clip fails
often or just needs a good clean.

You also should/might have a condenser on the side of the coil. To see
if this has shorted, just unplug the thing. It will run fine for a
while without it. It is there to suppress surges to the ignition module
and maybe as a radio filter.

Hope some of this helps,
