Another quick update:
Did an ECU read-out with OBD Auto Doctor (trial version) and found P1417 which is indeed throttle control related.
Possible causes
- Faulty Throttle control
- Throttle control harness is open or shorted
- Throttle control circuit poor electrical conenction
Like said before the symtoms are currently no longer there and I've checked TPS connection etc but didn't find any issues.
Not really a satisfying outcome but will use the car for now (engine light is off again) and see what happens.
Will keep you updated

Just a short update for future reference;
End of December I've cleaned the throttle bodies and IACV, been using the car on a daily basis since and did not have any issues anymore. I think that dirty/stuck throttle body/linkage must have been the root cause.
Thanks for all your support

Used some WD40 to clean everything, after that a little PTFE spray here and there to lubricate
