And then it would go away for another thirty miles. It felt loke
someone was in there pulling the wire off the coil occasionally. It has
no pattern - not related to ambient temperature, engine speed, or
anything.
And it's getting worse...I actually don't want to drive the car any
distance at this point, for fear of a long walk home. Any ideas? I'm
thinking it could be either fuel delivery or ignition (or both?), but
without a pattern, it's hard to reproduce when the car is parked. >>

Always start with the simple stuff. When was the last tune up? Look for a
fouled plug that is misfiring. Do you use di-lectric grease on the plug
wires to keep out corrosion? I've seen lots of engines that will idle fine,
and misfire under higher revs. Usually caused by a plug going bad or a set
of points wearing out.
A simple tune up - points, plugs, condenser, rotor, maybe a dist. cap -
should be the first place to look.
