Another thing to try is the distributor rotor arm.   They have a resistor
which gets burned out, especially the non-Bosch ones.  I had one go on a
cross country trip and was mystified for many miles by low power,
occasional bcking, and rotten gas mileage.   (Then was frustrated trying to
find a rotor in Montana...)   Bentley has resistance measurements for the
rotor and the ignition harness.   Now I always carry a spare rotor and cap.
