CIS-E problems 86 4KQ

[TM]

Kenny-
I am by no means a CIS expert, so take my words with a big grain of
salt.

My friend and I experienced a similar problem in his '86 VW QSW- same
engine
as your 4kq.

After checking all of the vacuum lines, replacing the fuel filter,
cleaning
the crankcase breather pipe, etc., it turned out that the fuel pump
relay and
the fuel pump needed replacement. After that, we still had some
problems, which
were due to a cat with broken bits clogging the exhaust. We gutted the
cat
as an emergency fix and got the car home that way.

I have an extensive writeup of that trip from mid-December 2001.
