RE: [DML] a few tech questions

["Jeff Friday" <DeLorean_Type304@xxxxxxx>]

Could be a number of things.

I suggest pulling the line off of the distributor Vacuum Advance to see if 
you have vacuum while idling.  You're not suppost to so this points to 
either:

A bad Vacuum Solenoid
A bad Thermal vacuum switch
A bad Microswitch

This could also point to a bad idle speed motor but I doubt it.  I had 
similar problems on a DeLorean here in NC.  Everything had been replaced but 
the microswitch and the problem persisted with the owner.  I took a look at 
the car and peformed the same tests as you with the same results.  Long 
story short Microswitch.

As far as the battery it could be a number of things but be sure to double 
check all your grounds and make sure they are snug.  I've seen loose 
connections before that only needed a snug and it solved the problem.

Let us know if any of this helps and I will offer other suggestions if the 
problem persists.
