I did this once. Its the TPS. They're about $34 to replace. When you clean a throttle body all the sensors need to come off too. Moisture will seep through the butter fly bearing and will ruin the sensor after about 2 days. I see you might have bought a whole new TB.. Sorry man but it was only a TPS
Honestly, I seriously doubt the GM dealership did the idle relearn correctly.
You have to do it with the key off, everyone does it while running and it doesn't do anything. A lot of times cleaning the throttle body will screw with the idle until you do the reset with the Tech 2. Just a guess tho lol
