running out of things to replace on 77

Well have replaced most of the sensors & switches. Put in a new thermotime and cold start valve yesterday, air regulator the other day - still had to let it idle to warm up for 10 minutes before I could hit throttle without afm popping and car dying out. **** - now what. Reset the idle and timing tonight and it runs fine while warmed up. I have a Calf. car but replace the afm with a federal used one which seems to be functioning ok. Running out of things to try. Any more ideas ?
Car definitely has a mind of its own. I do have a fsm so can refer to it if anyone has other ideas.
Thanks for any input.
