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.
