I did the exact same thing last fall at about the same mileage - never cleaned it prior. I couldn’t believe how much smoother it ran and the throttle response that it picked back up! It’s now on my routine maintenance rotation.

Glad you saw results. I didn’t at all.
Maintenance is not designed/supposed to always supply results. It is to "maintain". If let go long enough, a maintenance item will reveal negative results.
I remove and give mine a good cleaning every couple years, however in cold winter months if the intake hose is removed I'll clean it in-place using the following method:
-Turn the truck ON/ACC but not started (engine off)
-Use a floor jack to wedge the gas pedal firmly down where it will not move but open the throttle plate
-Use the step-kids or mother-in-laws toothbrush (whichever looks cleaner) and some CRC throttle body spray
I always notice a difference, especially if you find yourself removing oil blow-by on the bottom edge of the plate. Last step - casually place the toothbrush back exactly where I found it.
