This is probably unrelated, but my engine stalled yesterday, waiting at a traffic light. Motorists were not happy, but a bunch of big guys (off-duty firemen, I think) jumped on the car and pushed it to a nearby parking lot. while waiting for a flatbed, I was checking things, and noticed that there was a loose nut on the distributor junction block (near the coil- mine is a 1978.) we tried to tightened the nut to start the engine, then loosened it until the engine stalled, so we are sure that was the cause.
There were no lock washers on those nuts! installing split-washers were my first thing to do today.. Zed is now happy
How did they loosen over the winter?? Those nuts are, I think, the only things I haven't restored or replaced with new un-corroded ones.
I think I will invest in one of those tool rolls this summer. even my small visegrips would have fixed the problem.
