George, no idea exactly why, but if you are in west NH, three places that I've foudn that are good are:

1. Autex in Keene.
2. Gordie Davis (if he's still around, not seen him in years) in Marlow.
3. John's in Vermont (not sure the town, but I do know John is still working on 'em).

Where are you located? (I'm in the Monadnock region).

Done a compression test?

Clogged exhaust system?

Clean air filter? Some cars have junk screens before the air filter. If your van has a screen make sure it is not clogged.

Also you might want to check your injectors too.

Given good compression, in rank order I would check (with no reference to previous suggestions, so please forgive any repetitions):

a) Fuel Pressure - invest in or borrow a gauge for the purpose. They are invaluable diagnostic tools. NOTE: A FI pressure gauge is a serious bit of equipment, not the typical vacuum/pressure gauge of carburetor days. This gets you a good filter and clear supply and return lines when complete. b) Spark plugs, wires, distributor, cap, rotor and so forth. Leaky wires, carbon-tracks on the distributor cap poor connections, cracked connections, wrong gap, worn electrode(s) and so forth. c) Coil - Nice blue spark? Is the problem heat-related? Many VW coils had heat-failure problems. d) Check injectors. And run a few cans of Techron through the system on general principles anyway. e) Timing advance. Not sure how this is managed on that model, but it may take a timing light to verify.

My bet is fuel or spark related. Were I to place odds they would go as follows:

Fuel Related (clogged line or injector(s): 50% Spark/ignition related (wires, connectors, distribution): 25% Coil: 10% Injectors (if vehicle generally properly maintained): 10% All others: 5%
