There is no way to tighten it, and there is no set-screw, it just basically "snaps" into place, just turn it to the right until it stops and it should be ok. If not it may be cracked or broken on the bottom where it screws in.
Service Information 2002 Chevrolet K Silverado - 4WD | Sierra, Silverado (VIN C/K) Service Manual | Document ID: 1558786 #04-06-04-079: Increased Accelerator Pedal Effort from Idle Position (Clean Throttle Body and Adjust Blade) - (Oct 25, 2004) Subject: Increased Accelerator Pedal Effort From Idle Position (Clean Throttle Body and Adjust Blade) Models: 1999-2002 Chevrolet Silverado 2000-2002 Chevrolet Suburban, Tahoe 2003-2004 Chevrolet Express 1999-2002 GMC Sierra 2000-2002 GMC Yukon, Yukon XL 2003-2004 GMC Savana with 6.0L Engine (VIN U - RPO LQ4) Condition Some customers may comment on a higher than expected accelerator pedal effort from the idle position. Cause Condition may be caused by deposits in the throttle body bore and on the throttle plate. Correction Important: This procedure only applies to cable actuated throttle bodies on the models listed above. This procedure should not be performed on electronically controlled throttle bodies or on any vehicle or engine that is not listed above in the Models section. Important: TPS voltage cannot exceed .69 V. If the vehicle has an initial TPS voltage greater than .61 V, replace the Throttle Body Assembly. Verify that the cause for this condition is not a damaged or binding throttle cable. Remove the air intake duct. Refer to Air Cleaner Duct Replacement. Inspect the vehicle for installation of a fixed orifice PCV valve, refer to Corporate Service Bulletin 01-06-01-029B for PCV valve identification. Vehicles completing this throttle body procedure must use a Fixed Orifice PCV Valve, P/N 12572717. Clean throttle body bore and throttle valve plate of carbon using a shop rag and an appropriate cleaner. Refer to Engine Controls Repair Procedures - Throttle Body Cleaning Procedure. Select the correct plug for the size of the air bypass hole in the throttle body being serviced. Use a 5/32-inch drill bit to determine which plug to use. Vehicles built before introduction of the Fixed Orifice PCV Valve will have a 4.0 mm (.157") air bypass hole in the throttle plate. The 5/32-inch drill bit is smaller than the air bypass hole in these throttle bodies and can be inserted into the bypass hole. To reduce the air bypass hole in these vehicles requires the gray plug, P/N 12583703. Vehicles built after introduction of the Fixed Orifice PCV Valve will have a 3.65 mm (.144") air bypass hole in the throttle plate. The 5/32-inch drill bit is larger than the air bypass hole in these throttle bodies and cannot be inserted into the bypass hole. To reduce the air bypass hole in these vehicles requires the blue plug, P/N 12583704. Insert the appropriate plug (1) into the air bypass hole in the throttle plate. Insert the "tail" end of the plug through the throttle plate air bypass hole. (Refer to Figure 1) Open the throttle plate to allow access to the tail end of the plug. Pull the tail section to securely position the plug into the air bypass hole and trim excess material (1) from plug. (Refer to Figure 2) Turn ignition key to the on position, with engine off. Use the Tech 2® Scan tool to read initial TPS voltage. Using the Tech 2® Scan tool and a T15 driver to rotate the Minimum Air Rate screw, increase TPS voltage by .08 Volts (refer to TPS Voltage Chart below). Turn ignition key to the off position. Verify that the accelerator pedal moves freely - Depress the accelerator pedal to the floor and release. Install the air intake duct. Refer to Air Cleaner Duct Replacement. Start engine. Using the Tech 2® scan tool, monitor TPS voltage and verify the TPS voltage is no greater than .69V. Road Test Vehicle. Initial TPS Voltage TPS Voltage After .08 Volt Increase .45 V .53 V .47 V .55 V .49 V .57 V .51 V .59 V .53 V .61 V .55 V .63 V .57 V .65 V .59 V .67 V .61 V .69 V If initial TPS voltage is greater than .61 V – Replace Throttle Body Assembly Parts Information Part Number Description Qty 12583703 Plug, Throttle Plate - Gray 1 as req'd 12583704 Plug, Throttle Plate - Blue 1 as req'd Parts are currently available from GMSPO.

There was a bulletin out for the issue, came out years ago for the '99-'02 trucks. I did my '99 (which I haven't owned since '04) and my buddies '99 and '02 he had at the time. It involved plugging the hole in the throttle body butterfly plate and opening up the plate a little using a scan tool, Let me see if I can find it.
Nick, you won't be able to get both the NHT max-trailering package and Z71 package together, each package has their own unique shocks and springs,so it makes getting both impossible (Its always been like that since the NHT package came out in '06) Also I can tell you that the NHT package won't be available at the start of production, nor will the 3.0 diesel engine.
No, the 6.2 will be available in LTZ or High Country trim only just like the current trucks.
Looks like there are tow hook delete covers on your GMC that must be changed out..... Tow Hook Installation GMC (2014 thru 2018) Remove the LH/RH bumper bracket fasteners, (qty 16) and brackets. Upon Reassembly tighten fasteners to 58 N.m (43 lb ft). Disconnect fog lamp connector. Remove tow hook delete cover fasteners (qty 8). Remove tow hook delete covers. Install front tow hook covers, P/N 23243484 and 23243485 using retained hardware.Tighten Tighten to 6 N.m (53 lb in).
Cut it...... Tow Hook Replacement (2016 and Beyond) Chevy and GMC Crew Cab With Existing Tow Hooks Removal Raise and support vehicle. Driver Tow Hook Loosen tow hook through bolt and remove bolt out of frame rail enough to allow clearance for bolt head to be cut (qty 1). Cut bolt head off and remove bolt out of the outboard side of frame rail. Remove the rear tow hook bolt and remove the OE tow hook (qty 1). Passenger Side Tow Hook Remove tow hook bolts (qty 2)/nut (qty 1). Note: Passenger side tow hook bolts should not need to be cut. Swap rubber guard/seal from OE tow hooks to replacement tow hooks. Installation Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. Install new tow hooks (4) to frame rail (nut-qty 1 and bolt-qty 2 per hook) making sure that the through bolt head is facing outboard of the frame rail. Install the through bolt (3) and nut (2) and tighten to 80 N.m (59 lb ft). Install the short bolt (1) to frame and tighten to 80 N.m (59 lb ft). Lower vehicle.
Not much on my mind!
1. I'm a parts manager at a Chevy dealership, I sometimes help order and spec out new trucks for people that want specific options or items. 2. It has to be a fleet order, which shouldn't be an issue for most dealers, our sister dealership does fleet orders all the time for the city of Pittsburgh and Allegheny Co., along with surrounding cities/counties/municipalities. You can get Woodland Green as an SEO special order option, RPO code "9V5"....... 9V5 - Paints, solid, Woodland Green All normally body colored non-sheet metal parts will be Black. May require extended lead time. Door handles and mirrors will be grain Black. Deletes standard/packaged body side moldings. 1 - Requires (TGK) Special Paint and (01U) Special Paint.
