A/T 4speed fails, car wont move until hot.

that means the ECU can not control idle. the ECU is hard coded to 800, it opens the ISC to raise 500 to 800 RPM in servo loop actions. and holds it there like a rock ,even in DRIVE !

i have only one question why is the ISC dead.?
Dont know if that is the problem. What other test I need to do? I ve done the pinch test (passed), when going from D to N or P idles increases and then normalises and when turning headlights on RPMs blip but then come right up

i cant hurt
takes minutes to see, yes/no works
what is voltage now.? initial 13.77. Did not changed that much after 3 turns, idle yes voltage slightly from 13.77 to 13.81

OK. Now, what happened after driving her a bit longer. On stop lights while in drive and idling RPMs were 700ish on the lower side. The 800rpm were in parking at home after turning bleed screw CCW. I did the short test drive, set her in parking again and 800 steady. But on drive is not holding the 800rpm just like you said in above quote.
