Ahhhh, a solution!

[Roa, Greg]

Hello all,
I finally think I may have found the answer to why my car kept burning up
igniton modules.  Went to figure out the problem this evening, and checked
the values of the coil against what bentley shows.  Everything appeared in
spec.  I was getting 3200 ohms of resistance from terminal 4 (center pin, to
dist) to terminal 1, and .8 ohms between terminal 1 and 15 (pos and neg coil
terminals).  This matched up with the ranges that I was supposed to be
getting.
Upon closer inspection though, I noticed that the coil shown in the Bentley
was different than the one that I have in the car.  I had been using the
diagnostics for the 4cyl cis-e, as most of the tests are the same as for my
4kq, and bentley does not have any info for 5cyl cis-e cars.  Looking at the
specs for the cis-eIII cars, I noticed that it uses the same coil, and the
specified range between terminals 1 and 4 is 4000-5000 ohms.  So, my coil
had too low of resistance, and was shorting out the ignition module.  Yup,
I'm an idiot. 
Dropped the new coil in, and new replacement module, and car seems to be
running quite well.
So, I will test it over the next few days, and see how things go.  Thanks to
everyone, and thanks a bunch to Paul Cole.  He has been helping me out a ton
on this problem, and is a great guy, even if he is an electrical engineer.
; ) 
So anyhow, thanks to everyone on the list.  My car's ignition module thanks
you too.
