Cliff, I had a similar problem with my '84 and I was living with it until I could get a new exhaust system in along with new O2 sensor. One afternoon, the engine wouldn't start when I needed to go out. I had to do something, and my first check was the distributor rotor and cap... They were Brand X and not Bosch, and were really in bad shape. I cleaned them up enough to get going, but it took new cap and rotor to get things right.
