I had to disconnect my Mazda 6's battery and after that the idle at stop lights (or switching to neutral and releasing gas) jumps between 550-750 RPM few times, then stops doing that and stays at around 700. There's no DTC's. It never stalls.

After reconnecting the battery I let the car run for 20 minutes without any electrical load + 15 minutes with A/C on. Does the car need more time and driving to adjust the ECU with the TB and fuel trims?

I got a short video aswell:

The car is 2007 GG Mazda 6, 2.0L 108KW MTX.
