You can scan for error codes. Many auto parts stores have loaner meter for free. Call around Advanced Auto, AutoZone, VIP, NAPA, CarQuest, etc.

You can check for leaks in the intake vacuum hoses and other connections. With the engine running use a can of carburator starter sprayed on suspected places and see if engine speeds up. If so you found the leak!
NOTE: Do not spray starter fluid near or on hot engine parts or electrical elements, it will ignite very easily!

Have you check the fuel pump pressure ?

The repair for this is to scan the computer and see what codes are present if their are no codes indicating the TPS switch the problem will be your fuel pressure regulator.This is a fairly big job it requires removing the intake manifold if this is the 4.3L vortec engine.But Iam not sure which engine you have so this applies only to the Vortec Engine.

Vortec 4wd 2dr auto trans stalls while drive

you might want to look at your O2 sensors, they can cause the motor to run lean or rich. also you might have an electrical issue that is tripping your ECM. your electronic control module might be faulty. best solution is to get a trouble code reader and find out what your on board computer has stored. from there you can repair and clear the codes.
