Aileen,
  Don't know how similar your distributor is to my '84 1.9's, but you might want to check the secondary wires going through the distributor housing to the electronic sensor inside. Mine ran great  . .  then awful or wouldn't  even start randomly for a few years, until I was tipped off to these wires going bad and shorting to ground and wreaking havoc. Black smoke, stalling out, etc.
  Then I discovered this board, and that this was an all to common occurrence.

  This was a few years ago, but at the time, I was able to buy just the electronics and not the whole distributor.
  Good luck,
  Steven

  Hi there,
I am in search of an ECU for an 88' Westfalia. I need a Bosch with the
following # 0-261-200-065, VW# 025-906-022. Bought one, but it has a
different ECU # and a "D" after the VW #. My mechanic tried it, and it had
no effect. He would like to see one that has these exact #'s and see if it
helps. Never ending saga of my van running rich. Have checked all wiring to
and from computer, cleaned grounds, 02 sensor good, fuel filter good. Any
other ideas are welcome. Please let me know $ when you respond.
Thanks!!
