Les,

If you refer to D:04:10 of the DeLorean Workshop Manual you will see the "action circle" of the Lambda Control System. The constant idle speed system reacts to this cycle and varies the idle speed in direct proportion to the change in air/fuel mixture. 

Under ideal conditions (all systems operating to factory specification) the idle speed will oscillate during warm up. No oscillation during warm up is an indication that something is not at "spec". 

Here is my personal recommendation concerning this subject. The CIS (constant injection system) used in the DeLorean fuel injection system is fairly simple with a minimum of components and electric's. The disadvantage with this system is that there is little tolerance for defective components, electrical wiring and connection problems, or miss adjustments. Only experienced service personal, familiar with the DeLorean fuel injection system, should attempt to adjust the system to factory specification. 

As in Les's situation, if your DeLorean starts up easily accelerates smoothly and has good gas mileage you should probably leave it as is.
