Have you tried the ignition wires? Very common for aftermarket wires to have
shorted or open end. Next would be compression/leak down test. A bad intake
valve can cause all sorts of grief.

Has anybody had a problem with the 1,9 WBX in an 1985 GL.. where the left
bank driver side engine just does not work right.  Time is perfect, fuel and
spark... but number 3 cylinders plug turns black, number 4 hardly turns at
all... like there is not much going on in the cylinder.  Fuel pressure has
been checked,  injectors moved from the left bank to the right, and back,
new plugs and new wires.  Grounds cleaned many times, even double ground
straps.  Basically it is throwing raw fuel into the muffler where it is
burnt.  Mileage is around 8 mpg.  It has destroyed a new muffler.  The right
bank appears to be working normally.

  The cylinder pressures are for number 3  is 155 pounds, and cylinder 4 is
168 pounds.
This was a running engine,  that was taken out for a Subie conversion, then
put in my van several months later.  The original engine wiring  for the new
engine was kept,  along with ECU, Idle adjust etc, all electrical components
and wiring.  Evidently there is something I have not tried, but as I look at
it, only the valves and valve cover is all that is left on that side that
has not been checked.

Dave is trying to help me with this, I know he must be about bald, just
scratching his head... any ideals would be appreciated.
Thanks in Advance,
