I would next take a multimeter and see if the TPS has any electrical
dead spots in it's travel.

The green battery eye is just a prism, that reflects light until
the acid water level is low, and has nothing to do with state of charge.
Might clean the Throttle Position Sensor and step idle motor and
see if that helps your cold idle speed:

Re: Jeep Engine Stalls Just After Startup
 

I have a bit different issue with my 88 4.0 but I've seen the behavior
that you describe in several different cars over the years. It was
most commonly caused by a bad or gummed up Idle Air Control. The
motor and shaft would get gummed up or there would be a build-up
around the port that wouldn't let the pintle seat just right.
Usually, pulling the IAC off and cleaning it and the port in the
throttle body would fix the problem. For some reason, I had to
replace several bad IAC units in GM cars and they seemed especially
prone to getting crudded up. It's something cheap and easy to try, at
least.

My problem seems to be that the old Renix computer has a problem when
the temperature is in the 50-60 degree range and the engine is cold.
Spring and Fall, mine wants to die after driving a short while then
using the engine to brake down a hill to a stop. I finally gave up
and just tap the gas as I step on the clutch and write it off to
"personality".
