Did you inspect ALL of the electrical ground points on the motor and in the engine bay to ensure that they are clean and tight? Many otherwise unexplainable issues end up being ground-related issues.

Also, there maybe a TPS relearn procedure that needs a scantool.. or

How to perform a GM throttle body relearn procedure

Learn how to do a GM throttle body relearn to establish a new baseline idle after replacing or disconnecting the throttle body.

1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal.
2) After 3 minutes, turn the engine off and leave it off for 60- seconds.
3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods, you may see a check engine light. Scan for codes and if you get throttle body-related codes, clear them.
4) If the idle speed is still off, drive the vehicle at speeds above 44 mph and operate several acceleration and deceleration cycles. Then repeat step #3 one last time.

Good job @mikez71 .

Here is a good detailed video about the TPS install and how to clock it properly. Saved my asz.

And some pics of my TPS's, note the difference in the clocking of the sensor hub. Also those brass connectors can loosen up as well.

What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Might need the radiator side flaps.. Where does one find these?
