Once in a while after a drive w/o stopping for like 30 mins, when i come to a light and stop, i can hear/see the rev goes up and down ~+/- 20-30 or so and can hear it also for about 5s. Any idea ?

I had this problem and after I had the idle control valve replaced everything was fine. Might be the place to start looking.

New throttle body solved my problem.

I dont have any CEL or any lights popping up or power loss. Only happen sometimes. Maybe get it vag and check out the codes or sth.

Try doing a TB adaptation first, but chances are it's an iffy stepper motor in the TB.

Brand new TB on my car did this...swapped it with the original unit (which had been causing some cold start driveability issues) and it stopped.
