bucking bronco

Defective ignition wires to plugs will produce this symptom. How old are
yours?
Wires will fail when its wet. Sometimes they fail under load . . idling and
low load is fine . .. step on the gas and one or two cylinders will start
missing. Something to do with increased resistance at the plug under load .
.. I havent figured that one out yet.

Also, redo(clean) all the ground points around the ignition coil and the
back of engine. Bad grounds will give you weird symptoms also.

If your plugs, dist cap, rotor and wires are more than 5 years old, I would
just change them on general principles . . . its old enough.
