[DML] Bouncy idle speed

["dmcchaser" <dmcchaser@xxxxxxxx>]

Hello again.
  Well, i've finally corrected my high idle problem, however, I think
I've uncovered some other issues.  I've set the idle speed, mixture
and timing according to the service manual, using an exhaust analyzer,
rpm meter, and dwell meter across the mixture control solenoid.
  
  Here's what happens:  On a cold start the idle bounces heavily,
about 300 rpm or so up and down.  Once the car warms up to operating
temp the idle still fluctuates but less drastically, maybe 50 rpm or so.
It seems like the lambda system and the idle speed control system are
fighting each other.  Is this a characteristic of our cars?  What can
be done to correct or lessen this really annoying condition?  

  It's kind of embarassing to walk out to my car with everyone
watching, start her up, and Vwoomba, Vwoomba, Vwoomba, Vwoomba goes
the idle... sigh...
