Why did my Sierra 5.3L throttle body change?
You said the throttle body was really dirty. The ECM made an adjustment due to the carbon build up on the throttle body. When you cleaned it, you caused a sudden change to the throttle body function and confused the ECM. It should readjust after about 200 miles or so and be back to normal. You need to take a road trip.

How can you tell if your Silverado throttle body is bad?
As your Silverado’s throttle body opens, the various sensors in your Silverado measure the air coming in, and oxygen content coming out. If any of these sensors goes bad, it can feel the same as a bad throttle body. That’s why getting the trouble codes is so important. It can really narrow down what you are looking for.

How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
When do you know your throttle body needs cleaning?
When your throttle body is operating below its normal effectiveness, one of the tell-tale signs is a poor or low idle. This includes stalling after coming to a stop, a low idle after starting, or stalling when the throttle is pressed down rapidly. Dirt causes airflow into the system to be turbulent and leads to a fluctuating idle speed.
