The throttle cable is new and the operation of the pedal and linkage on top
of the throttle body is unobstructed. In addition, i checked the throttle
position switch under the throttle body with a VOM and the switch operates
as it should per the Bentley manual. Thanks.

Rico,
I know this is random, but have you checked you throttle cable and gas
pedal...? The reason I ask is I had idle issues with my subie conversion.
Last week the bottom of the pedal gave way, the rivets holding it in place
were dust...I think the pedal was going for a while, thus not allowing the
throttle cable to work properly...
I fixed it, idle issues gone...
I may be way off, but I figured I'd share
Good luck,

Yesterday, I was backing out of the driveway in my 87 Vanagon and got to
the end of the driveway. When I started to drive down the street the van
suddenly began to run died. I was able to restart the van only by holding
the accelerator pedal to the floor and cranking for about 20 seconds. The
van ran only about 400 rpm and had very little power. I checked the usual
easy fixes. The spark plugs were old and I replaced them, the distributor
cap, and the rotor. I was able to restart the van but now the idle is
about
3500 rpm.
I checked:
the temp II sensor, the resistance measurements were at the
specifications at the temperature ranges specified in the Bentley manual.
I checked
the temperature of the sensor with my nifty new VOM that has a temperature
probe so I was sure of the temperature at which the measurements were
taken,
the idle stabilizer control valve. I cleaned the valve and get the
appropriate humming and opening and closing of the valve,
the fuel pressure (the pressure at was about 32 psi),
I disconnected the oxygen sensor in order to reset the ECU to the
default mode,
I cleaned and tightened the grounds in the engine compartment, at the
transmission and frame ground attachment,
I set the timing with a timing light per Bentley with the temp II
sensor disconnected and the idle stabilizer control valve disconnected,
I used some metaphorical language,
I checked the vacuum and it was about 22 on the vac. gauge at the 3000
rpm level,
I cleaned the connections on the idle stabilizer control unit as well
as soldering a joint that had a small crack in the where one if the pins
from the plug attaches to the board,
I used a little more metaphorical language.
The van still idles around 3500 rpm. Any suggestions would be
appreciated.
