Steve,

Unless it is doubling as the CAS return, it is hard for me to imagine the
shield being critical if it is only missing in an area well separated from
other wires carrying pulses of significant current such as the coil power or
injector wires. But I'm no expert.

Having extended the wires, the possibility exists that the two CAS signal
wires have been reversed or exchanged with the CAS return.  I'm sure you
have already checked this out.  Just for grins, I'll reverse the wires on my
system and see what the effect is.  I can see Tracy's poor EC2 cringing
already, wondering what it did to deserve the treatment is gets from me.

Steve,
Thanks for the information. No resolution yet. I gave up yesterday, and watched a little football, then went out to eat with my wife.

Good suggestion with the spare CAS, I can give that a try, perhaps even rig it up somehow to the cordless drill or something.

I had one thought today, while thinking about anything that was different. On the CAS, the shielded wire used to run all the way to the CAS, but in the process of re-routing the wiring, I extended the CAS wires about 12 inches with regular aircraft wire (non-shielded). I am wondering if that is causing the trouble. I was thinking that I could shield it for a test, with aluminum foil, and use a clip to ensure good connection to the existing shield. That should work good enough to see if that short section of unshielded wire is the culprit.

Any opinion ?
