I have a 06 997 S which i bought about 3 months ago and have alil over 2700 miles. after driving it a while today i noticed that the rpms were moving up and down and the car kept bogging as i gave it gas. this happend for about 30 minutes and then jsut stoped. Has this ever happend to anyone, should i be concerned, what can it be, should i take it in to the delear now or wait and see what happens?

 

There have been similar incidents repoted on other forums. Problem seems to arise shortly after refuelling and is often fixed by:

1. turn engine off
2. open fuel cap
3. start engine and run for few minutes
4. put fuel cap back on

Or take it to the dealer and have the software flashed with the most recent code. At least that's what my service tech told me they did to mine.
