A couple of years ago I had trouble with a hesitation and miss that I couldn't track down, then one day going over connections and and vacuum hoses I stumbled on a corroded ground near the driver's side headlight. I cleaned it up and miraculously all my troubles cleared up.

I posted this revelation here and an excert appears in the FAQ now. At the time Lucid posted that that ground has nothing to do with fuel injection and therefore shouldn't have been the cause or solution to my problems. Well, 2 years later, I think he's right. I had been keeping notes on all the chages I had been making, trying to fix my problem and checking my notes I realized that I had removed the distributor cap and cleaned the shaft that day too.

And that leads me to my questions: I have been able to affect this grounding issue just by removing and replacing the distributor cap (loose wires get jostled? - checked that a dozen times).

I noticed that the distributor shaft has considerable vertical play (it's an old 240 style distributor mounted vertically near the front of the block) - could this cause any problems?

After I replace the cap I noticed copper oxide (or greenish powdery deposits) at the electrodes within a few hundred miles. They appear only at one edge of the electrode - is this indicative of a flaky connection somewhere?

Finally, I have checked and removed and replaced every ground I can find, but am thinking of splicing into the coil ground (Rex/Regina) and giving it it's own ground - is this a good idea? Is the black wire from the coil ground?

I would really appreciate some input on this one.

Thanks,

Ron
