Hey guys (again),
It seems my car is doing something strange, so I'll need your advice

I was driving normally and today I noticed something weird. Let's say I'm on 3rd gear, and then I put neutral and slow down. The revs are falling to normal RPMs but then it's going to 1.5k or something, by itself. If the car stops moving, the revs are back to normal RPM again. I recently had oil and oil filter changed and Porsche said its a well maintained car. Also, there is no engine light or error code and my gas is always 100 Octane.

EDIT: It only happens if the car is moving with neutral. If it stops, the revs are falling to normal

Any ideas ?
Thanks
