What is a throttle body alignment?
This procedure cycles the motorized throttle body through various states (idle, part throttle, WOT) to relearn their positions. Some examples of reasons to perform a TBA: The vehicle’s battery has been disconnected and re-connected. The ECU has been removed and reinstalled.
What problems can a throttle body cause?
When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle.

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.
