Idle problem, please help!

okay, i have a 91 Z28, it has a bad idling problem. only when it is warmed up though. when i first start it up in the morning, it is fine. but then after about 5 mins, it starts idling rough and wants to die. i have replaced the tps, the idle/air control sensor, the oxy sensor, and many others. if you can help me out, please do.
