1991 gm 305 engine stalls at idle and slowing down

I have a 1991 cadillac fleetwood brougham that keeps stalling out idleing or when slowing and coming to a stop. Also is worse when warm and when ac is on. The injectors are spraying, when I disconnect the throttle positin senso and air idle thing it does make a differce on the idle it get loud and rund faster so I guess they are doing something. I have also disconnected the erg hooke it to stay open also with no difference.
