Well, stop wasting your money on 100 octane.
Why are you coasting at speed?
Make sure your floor mat is not infringing on your gas pedel. Probably something more complex like TPS or MAF Sensor.

You only need 91-93 octane. Are you in the USA? Include your location in your screen name/avatar. Find a quality Porsche specific indy shop in your area for help. Don't go to the dealership.

I'm in EU. Thanks for the input. So what do you think the cause is, for the high rev?

I think you need to post your location, and seek/ask for a recommendation for a Porsche specific indy shop to help your repair. You can also cross post on the 986 Forum at Rennlist.com and Renntech.org. Good luck.

Thanks guys. After all it was an AOS issue. I had it changed on Official Dealer for 145 Euros. Just in case anyone else had White smoke on startup and Engine light and auto-Revs.

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 |

You said earlier there was no light. Now you say you had a CEL. 
You also NEVER told us you had white smoke (which does NOT alway mean AOS).
Glad you're fixed.
