91 idel issue

My 1991 gmc with the 5.7 engine with the TBI is all original to my truck. At start up the engine just keeps shutting off. it will not idle. once the truck warms up idle goes back to normal. when pressing the gas peddle from a stop the engine wants to cut back a little. what is going on here.
