Weird, but unlikely to be related. There is no sensor for low coolant.
I have started and run (for a minute or so) my engine when it has
been totally dry Air in the cooling system does seem to be
a contributor to erratic (loping) idling, although I have yet to figure
out why this happens.

Hey Jondee,

I don't think its coolent level itself, I think that when the coolent level drops so that there is no coolent near the temparature sensor, the tempature sensor gives irratic readings and the ECU gets confused. In my case I think its actually the engine getting flooded because of this and the flooding causing the starting problems.

The idling you mention is what i've experienced before aswell.

Running a 4AG at idle without coolent, daring! Actually I think these engines can take alot. the oil cooler takes the blunt of the cooling in that situation and toyota engines are notoriously relyable. My sister had a faulty radiator in her Starlet couple of years ago, her fix was just to wait until all the coolent had evaporated, when it stopped giving off steam she figured the problem fixed and drove the car home.
Offcourse this meant there wasn't a drop of coolent in the car

Engine survived this treatment a few times until the radiator was finally replaced.
