If you have a short piece of wire you can bridge the two connectors in the
temp II plug and this will allow the van to run well. It will run a little
crappy and you will have to hold your foot on the pedal when it is cold but
once it warms up (just a few minutes) it will run like normal. I was taught
this by Darrel Boehler on a trip a couple of years ago. Worked like a charm
in my 89 Wolfsburg. You have to be careful in the 1.9l Vanagons though. I
have found that many of them have a problem that seems like faulty temp II
but it is actually the wire going from the computer to the Temp II that has
become faulty. It gets a high resistance and then no matter how many
sensors you put in, the van will still not start when hot, run rich when
warm. Also a faulty or non-existant ground strap to the engine can cause a
high resistance reading. Checking these with an Ohm meter takes a Bentley
manual and about five minutes of time. People think I am a miracle worker
when I can diagnose their van after everyone else has given up on it. I
tell all my customers that I have a better survival rate than any doctor. I
have never lost a patient! :-) 95% of the time they could have diagnosed
it themselves with a little patience, a Bentley and an Ohm meter, but don't
tell them that :-)

Assuming I do not carry a spare temp-2 and I have this failure far from
home... would one of these be the correct work-around to get a hot engine to
start and not run rich:
1) Disconnect the Temp-2 sensor?
or
2) Disconnect and connect the 2 leads (are there 2 leads?) together?
or
3) Disconnect and ground the 1 lead (is there just 1 lead?)?
or
4) Other or no work-around?
