[s-cars] New faltering problem

OK, I guess I better chime in. I have the home brew 1.8 coils, and  
they work fine - now. However, when I first put the wires together in  
a nice shrink tubing sheath, it looked great - but, I had a miss  
(even at idle) on apparently one cylinder. Thinking I may have a bad  
connection near the back of my group of wires (since thats where most  
of my connections were, I started separating and wiggling wires to  
find the culprit. What I found was that all the connections were  
apparently good (they were all soldered, so I expected them to be  
good unless they got really hot). I also found that with the wires  
grouped together, I get a miss, and with the wires separated, it runs  
great. My solution was easy - I left them separated, and the car has  
run fine for the last couple of years. I suspect there's a shielding  
problem that we really don't know anything about, and that if each  
wire had a grounded sheath, the problem would go away, and we still  
wouldn't know exactly why.
For what it's worth,
