[DML] Interesting idling stuff

[Enid/Jeremiah <hispanicangeleyes@xxxxxxxxx>]

Ok everyone - I have a question.  I have eliminated
the idle control motor due to my problem I'm going to
describe here.  With my idle control motor
disconnected, the car idles at 900 rpm beautifully
(the ecu is hooked up).  If I hook up the idle control
motor (keep in mind the ecu has been hooked up the
whole time), my rpms jump from 900 to almost 2500
rpms.  I acquired a spare idle control motor and tried
that one (one off another owner's car that I KNEW
worked), and my car jumped in rpms again.  So then I
obtained a spare idle speed ecu that I knew worked -
hooked it up - my car's idle jumped again.  So I've
tested both new ecu's and motor's with no success.  We
have rebuilt the whole engine from the block up, so I
know all vacuum hoses are intact, all O-rings are new
and replaced, the intake manifold is on propery.  

Heck, before we rebuilt the engine the tube that goes
from the idle control motor to the mixture control
unit was OUT and the car idle'd fine.  Now that tube
is hooked up properly, and it jumps the rpms now -
very unusual.  I have hooked up a Bosch K-Jetronic
Fuel Pressure Gauge Tester to my system - the CPR
pressure when WARM is good; I have not had the
opportunity to check it when "overnight" cold (since
the gauges are not mine).  The fuel distributor
pressure is dead on.  I know I have to replace my fuel
accumulator, but I wouldn't figure that would cause me
idling problems.  Any ideas, anyone?

Oh, just a clarification question...  does a dead fuel
accumulator keep you from cranking up when HOT or
"warm"?  If I have the car hot, turn it off, and
crank, I can fire right up.  If it's "warm" - 1 to 2
hours - I have to swap the CPR and cold start
connections.  I just want to make sure that it is the
accumulator and not some other unusual problem.
