88 bronco engine stalls

i have a 88 bronco ,351 EFI that stalls at stops after it is warmed up. i've checked for loose vacuum found nothing, changed the IAC motor , O2 sensor, MAP sensor and still have'nt figured it out. i've also replaced the throttle body and adjusted the idle control too compensate ,it helps for a while but then goes back to stalling. anyone got any ideas??? also this one had a IAC idle block spacer that i removed that seems too allow adjustment of the IAC idle for some unknown reason? anyone know why this is?
