These trucks were equipped with a TBI, (Throttle Body Injector). This looks like a modified Carburetor with two large fuel injectors placed over a two barrel throttle plate and venturi body. You need to check the base gasket on this TBI Unit. The base gaskets were notorious for becoming brittle and cracked . If you remove the air cleaner and open the throttle plates you may see a chunk of black hanging out down below the throttle plates. If you see this, this is the base gasket and it cracked and needs to be replaced.
The Idle Air Control Solenoids were also an issue on these truck too. This is a round part that will have a plug on it normally near the base of the TBI Unit. This will just require a quick replacement.
The last thing that it might be is the electronically controlled EGR Valve. This valve used to cause some trouble from time to time, and I know there was a warranty campaign on these parts. the valve will need to be replaced or cleaned if this is the case.
Good luck and hope this helps friend, Keep me posted and here is a link for you to retrieve DTC codes. http://www.troublecodes.net/GM/
