If you want to see if it is the Temp II sensor there is an easy test you
can do. Unplug the temp II sensor (blue plug on thermostat housing).
Then get a short piece of wire or a paper clip and jumper the two prongs
inside of the plug to each other. Now start the van. You may have to
hold your foot on the gas to keep it running until it warms up but after
it warms up for a couple of minutes it should run well. If this fixes
your problem then it is your Temp II sensor that has gone bad and should
be replaced. Darrell Boehler gave me this trick when I was away on a
vacation one time with no tools or anything. I got a new sensor from
the local dealer for around $9 that same day and was back on the road.
Let me know what you find.
