So I followed a video on youtube, looked pretty straight forward. Hold the TB blade open (by hand), wipe out the crud, be careful of how much TB cleaner you use. So that's what I did, for the most part I sprayed the cleaner onto a rag and wiped all the gunk out. Started truck, it idled fine so I clocked back in and went back to work.

Well, it might have been better if you had used the gas pedal (key on, engine off) to open the butterfly, for cleaning. Even then, the gunk removed may have resulted in more than one re-learn attempts to get things back in order.

Step 1 – Open hood and pop off plastic engine cover

That behemoth of a top cover on your Vortec V8 is held on by only two tabs. Gently lift the front until it pops up from its post, then reach under and toward the rear of the cover to pop the back tab. (It's so easy, a US Congressman could do it!)

Step 3 – Remove air intake tubing

At each end of the intake tubing, you'll see a worm-drive clamp. Loosen both clamps at the air cleaner and TB unit. There will also be a tab at the far left side rear. Simply pop that off. Finally, unplug the sensor plug on the intake tube.

Step 4 – Remove power leads to the throttle body

Simply push down on the gray clip tab, and remove the entire plug. You should not have to remove the pink clip.

Step 5 – Remove the throttle body assembly

Using a 10mm wrench, remove the two nuts and two bolts. Then, slide the TB off the studs.

Step 6 – Inspect O-ring and replace if needed

The O-ring should be intact; however, if it has any cuts, abrasions, or is just plain grungy, you should have a new gasket in the new throttle body kit.

Step 7 – Install the new (or refurbished) throttle body

Simply line up the stud screws and slide the unit in place. Tighten the nuts and lower bolts in a crisscross pattern until tight. Do not over tighten! There is no torque spec for these, so use common sense when tightening. Plug the sensor plug in, and secure it with the gray clip.

Step 8 – Reinstall air intake assembly and cover

Install the plastic air intake tubing assembly, tighten the worm-drive clamps, and push the PCV valve back in place. Simply line up the front and rear tabs on the engine cover. Then, push down firmly until it snaps into place. Plug in the sensor at the air cleaner end of the intake.
