Default rough idle then high idle

Right after adding 1/2litre of oil yesterday. i restarted to check the level and the car sounded like it was gonna shut off! it finally evened out but the rpm rose to 1700 turns...making it impossible to check the level. this went on for 15-20 minutes, i tried shutting the car off an on again several times but the problem was still there. i finally let it rest for 20 minutes started it and again the rpm went up, this time i took the car for a serious(spirited) ride...full throttle every where, the car has been fine ever since... any explainationsÉÉ. thanks

Which car? 997.1 or 997.2? what was the oil gauge reading before adding oil?

Ask your dealer, it could be the MAF sensor.

Check the oil filler tube cap for a leak even though it is tight on the tube.
