Richard,
       I am assuming it runs good after it is warmed
up?   You need to provide more information.   But if
this is the case I would check the plugs before you
start the vehicle.   Perhaps you have a leaky injector
that leaks after you shut the van off?

Subject: Continuing Cold Stall Problem - HELP!!!

I've noticed a rash of cold start problems on
wasserboxers lately on
this
list. My 87 has had the same problem for a while. So I
replaced the
temp
sensor near the thermostat...replaced the
thermostat....unplugged the
oxy
sensor (no change).....plugged back the oxy sensor (no
change)....

So last week when the wisdom of the list said "replace
the idle
stabilizer
valve" I decided to try that. I "borrowed" the
stabilizer from my
wife's 90
cabriolet. Put it in the 87 (I put the 87's old
stabilizer in her
cabriolet. Her cabriolet runs fine...the 87 still has
the problem with
bad
idle when the engine is cold.

Obviously the 87 is running rich at cold start...I can
see the black
smoke...I can smell the excess hydrocarbons....and the
engine runs
rough
off idle until the plugs burn clean...

So what do I do next????   AAAARRRRRGGGGG!!!
