start up/idle issue

car started doin this the other day......

when i start the car up the afc will read 5% throttle and idle around will slowly progress down to 0% throttle and then the idle will finally drop back to 7-800.......after the first time i hit the gas and move the car the car will idle back to 1100 for a couple seconds, the afc will read 0% throttle, then it will fall back down to 7-800........then every now and again coming to a stop it will idle high again......sometimes in higher gears at lower rpms it feels like the car hangs.......the tps wires have been replaced and that is not the thinking either a tps sensor itself or the iac sensor
