Answers :

Very good chance that it's bad fuel injectors and/or fuel pressure regulator. Very common with the 96-2000 L29 motor (Vortec 7.4L)
Replace with better injectors, the OEM ones are NOT WORTH cleaning. Go to http://www.fullsizechevy.com/forums/general-discussion/technical-maintenance/213662-96-99-454-vortec-owners.html
