<x-flowed>Sounds like either a bad condenser or coil.

Couple weeks back, I shame-facedly admitted to you all that I'd screwed up something, while conducting a high-RPM acoustics experiment inside a tunnel... couple seconds of overzealous revving led to a semi-consistent miss/sputter, the cause of which I could not isolate.
After normal tune-up procedures, the symptom disappeared, and daily driving resumed. Had the good fortune to be working very near home for a few weeks, so never had to use the freeway.
'Til yesterday, when I did about 50 miles at a steady 60-65 mph. Once back on surface streets, the identical problem resurfaced.
Here's what I found when I got home: A lot of silvery dust inside the dizzy cap, and a large burr on the fixed point. I'd noticed a little bit of this dust last time around, just blew it away and went about my business. But now there's a ton of it, on points and plate and shaft and all over the inside of the cap.
Filed the burr, reset the gap, swapped in a clean cap and rotor, and the car's happy as a clam.
But what's with the metal shavings? And how does speed/RPM factor in?
