What is your idle rpm when your engine is warmed up and able to idle on its own? I would disconnect the negative battery cable for 1/2 hour, then turn the idle screw clockwise between 1/8 and 1/4 turn, reconnect negative cable and run the car for a few days, it takes time for the computer to relearn and see if this helps. It sounds like your on the threshhold of idling and stalling so a little turn of the idle screw might be your solution.

Adder is right. Its been covered a million times on here. Search a little more and you should find it. Ill give you some really good hints. Iac, maf(if its a maf car), base idle reset procedure.

clean the idle bypass value, if not the fix replace the TPS on top of the TB. 90% of the time this fixes unless heavy abuse. Did have a car on time work when cold, not start when warmed up....it was both 02 sensors.
