Over the past year I have had a lot of troubles with the fuel injection
system on my 82 air cooled Westy.  The symptoms included a very weird idle,
hard starting when cold, and finally progressed to an intermittent extreme
rich running condition that totally shut down the van (see below for more
info).  I have sent in several messages to the list asking for help and I
received the standard responses: check the temp sensors, check your grounds,
test the FI per the Bentley, etc.  Well I did all that, and everything
checked out fine.  By the process of elimination I began to suspect the ECU.
This suggestion was met with a good bit of skepticism by several list
members.  I finally managed to track down a reasonably priced used ECU and
presto, problem solved.  It is nice to have a running van again!

On the road again,
Jake
