Hi everyone. 88' Vanagon still running very rich, stalling on idle after
much troubleshooting. Sounds like it is being smothered and eventually gives
out. Also puffs of black smoke and black oily guck coming out of tailpipe.
 I have done the following:
Tested 02 sensor-ok
New Temp II Sensor
Replaced Idle Stablizer Unit
Replaced ECU
New Fuel Pressure Regulator
New spark plugs and wires
All wiring from ECU to 02 sensor checked-ok
New ground strap and Starter (just for fun)
Idle Control Valve "seems" to be vibrating. But could be the bucking and
puffing of engine. Hard to tell. Never felt it and had someone go, "there,
it's humming."
Throttle body clicking as it should on idle and full throttle
New air filter
New fuel filter
New fuel lines (again..just for fun and safety)

I got a Digitool, tried my hand at installing it, and the ECU gave
out-completely. Had to get another ECU (can you hear the violins?).
Scared to install it on my new one.
 Am I looking at testing/replacing the AMF and Idle Control Valve? Any hints
on how to test these? Have the Bentley and just need a bit of coaxing and
help.
Thanks all, you have given some great pointers before with this van, hoping
that I can get it going.
