[DML] idle problems

[Phil Priestley <phil@xxxxxxxxxxxxxxxxxx>]

My car is acting real strange. When you turn the key it starts just 
fine, then as it settles down to idle, it spits and sputters and acts 
like like it's starving for fuel. It runs fine when you are driving it, 
but spits and sputters and shakes at stop lights until it gets fully 
warmed up, then the idle starts bouncing around on it. When you turn 
the key and the fuel pump  pressurizes the system there is a loud thump 
on the rear passengers side when it shuts off.
It doesn't act this way all the time. Once out of the 5 times i started 
it yesterday it idled just fine.

It has a new fuel pump, injectors, idle speed motor, idle speed 
thermister, temperature vacuum  switch, fuel accumulator, and fuel 
filter, plus a rebuilt CPR from John Hervey. I think the only parts 
that aren't new in the fuel system are the fuel relay and the frequency 
valve. The intake manifold o-rings were just replaced and I can't find 
any vacuum leaks. I'm almost leaning toward the CPR being bad because 
it started this all of a sudden and it seems to mostly go away after a 
bit. It's almost like there is not enough fuel pressure till it warms 
up and then it seems like it bounces around. . The timing is right on 
and the air/fuel mixture is real close. Anyone got any ideas? I need to 
get it running right for a parade at the end of the month.

I would like to avoid taking  it to the german auto repair shop and 
have them run tests on the CIS.
