<<Subject: vanagon syndrome-- need capacitor
Hello, I think me 85 has this syndrome.I have all the symptoms and they
have been getting worse recently, I also have stalling at start up
occasionally, where I never had this before. Gotta do something about
it.>>

Prior to going to the capacitor extreme in trying to get the Van running
right off idle, make sure the thottle positioning switch is coming on at
the right time as well as off.

If it isn't setup right on the money you'll experience all the problems
you've mentioned in spades.

I'm not sure if you have an early or late model 85.
The early version has two TPS switches, the later version having only
one.

They had better be adjusted properly or your going to get the off idle
stalling, bucking, problems you mentioned.
