Hopefully your trouble code will tell you which cylinder, like p0302, cylinder number 2, check fuel--spark--compression on that cylinder. If you get a p0300 code, means the computer thinks there is a misfire, but, can't identify which cylinder?
How long since overall tune-up? Spark plugs and wires are great, as far as it goes.

    This is very complex , first thing is have the vehicle checked for DTC'S - diagnostic trouble codes stored in the BCM , PCM !
    The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the throttle actuator control (TAC) motor in order to maintain the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Descriptionfor the 4.3L engine or Throttle Actuator Control (TAC) System Description for the 4.8L, 5.3L, 6.0L, 6.2L or 7.0L engines.
    Your best bet would be to take to the dealer !

    Of the cuff, I would suspect bad gas. It sounds as if the truck has been seldom driven, and may need a gas additive to "revive" the stale gas.
    Some people would put about 10 gallons of "premium" gas in it to see if that would help.
    God bless your efforts.

    First off where does the clunk come from, the front or center of the vehicle? It could be the transfer case/ front differential oil needs to be checked for leaks or low oil levels, or a universal joint worn out from transfer case to front differential.
