I just went out and popped the distributor cap off. I discovered that the
hall effect sensor (if that's what the plastic thing at the rear is) is
cracked loose at its base. Put the distributor back together and started the
car and wiggled the set of wires going to the sensor with a pair of
insulated pliers. The idle improved, but only somewhat.
Is this a plausible reason for the poor running? I checked it because I was
going over every connection disconnected and reconnected for this project.
