Assume you have a 1.9L??? What year is your Vanagon?

The way to test the DIS is to bypass it, and see if the idle stabilizes, if
you have been running the van that way for two years, and just recently had
an issue with stalling, my guess is that your problem isn't related to the
DIS but something else like:

AFM or Vacuum leak
Bad or corroded wires to any of the large number of sensors in the engine
area
Failing distributor or rotor
Plug wires
Bad ground or Vanagon syndrome
Dirty injectors, fuel filter, plugs
God forbid, bad heads (do a leak down test checking engine compression)

Subject: Bypassed DIS

So I just discover that my van does not have the DIS (Digital Idle
Stabalizer)and has been bypassed by plugging the two plugs together.  I've
only recently starting working in the engine area, fuel line replacemet,
clean grounds, etc....  I've had the engine die when coming to a stop and
then not starting the past few weeks which is why I've been spending time in
the engine. (enjoying the learning process)  While reading posts and
researching topics found out there is no DIS and van has been on bypass
since I've owned her.  Almost 2 years....



My question is once I put in a new DIS and then calibrate the idle per
Bently is there anything else that I should be concerned with due to the
bypass?  I don't know how long it's been this way before I purchased the
van?  Anyone have any experience with this?  Thanks...
