It was the Distributor !
I drove the Metro into town today, went shopping and Garage sale'ing and not one single cough or miss.
Must have put 90 miles on it, starting / stopping, killing the engine innumerable times, starting it up, up hills - down hills -
all the conditions where I saw intermittent missing before and it drives as it used to before last winter.
The Distributor is the LAST THING I would have thought causing the intermittent missing.
Especially with it not having any obvious defects in the rotor vanes or the coil's appearance.
I must assume it is the electrical coil within it that is 'bad'.
Murphy's Law.
So - I hate to toss the old Distributor in the Trash.
Don't know who would want it, though.
Wonder if NAPA would send it back to whoever rebuilds these things for Metro's ?
Shame to toss it.....it is a nicely machined piece of equipment and becoming rarer each year.
Unless the Metro starts acting up again in a while - this should be the end of my tale.
