Ed, congrats on the car passing.  I seriously think
the jurry is still out on the CIS-III ign combined
with turbos.  I personally never trusted it, and there
have been a multiple people that have ended up with
blown head gaskets using that setup, me included.  The
damn thing just has a mind of it's own, and I swear
that even though you have taken every step to make it
think the original engine is there, it knows you're
toying with it.

You asked what you could do next?  New engine
management my friend, you will not regret it.

Later,
