I am going through several past posts concerning heistation/fi problems in
hopes of curing my particular problem (84 1.9 that stumbles at certain
points during acceleration--for instance, when increasing rpm from idle, it
stumbles at about 1300 rpm then steadies at 1450 rpm).  I need elaboration
on two related posts.  The first was made by Steve Cotsford a few months ago
in response to my own inquiries about a ECU burnout leading to the death of
my last engine (sorry, I can't find Steve's email so, Steve, if your out
there, this is for you).  Steve mentioned that he had a bucking broblem he
solved by rewiring the aux air regulator to prevent it from depriving the
fuel injectors of their groud.  Steve, how did you do this??  I found the
hidden connection you mentioned and have identified all wires involved, now
the question is where to re-route the aux air reg lead.

The second related post was made by Mark Keller in June and included a
summary of a vw bulletin concerning fi troubleshooting.  That bulletin also
mentions the problem of the hidden connector and advises that the wires be
soldered:

Fuel injection wire harness internal connections (injector power and ground
terminal #94, G1 and G2) butt type connector inside the harness cover can
also be a problem. Intermittent missing in lower gears and some at highway
speeds. These three connections are to be soldered. Refer to harness checks
in the microfiche or the Digifant I & II ProTraining manual, pages 40-43.

Does this mean that the connector should be removed and each wire soldered
to each other--i.e. duplicating the effect of the connector, but with
solder.  Or does this mean to solder the six wires into two wire
groups--each wire being soldered to only one other?  If this is the case,
which wires go together?

Any suggestions--from Steve, Mark, or anyone else in the know--would be
appreciated.

Many Thanks,
Seth Bruggeman
