Ah, I see. Well then you can disregard ALL of that... haha
But I would say take it to your dealership, and take the service writer for a drive. Point out what it's doing and make it clear to them. Or have them drive and point it all out to them.
If you feel up to it you can check out your air filter and throttle body. Even look at the MAF if you want. the MAF sensor shouldn't be dirty. But the TB could be. Mine was pretty dirty at about 31k
It could just be the right amount of gunk in the right spot. You can get Throttle Body cleaner at any auto parts store or even walmart and such. Just follow the can's directions.
Or just take it to the dealer, Your car should still be covered by the powertrain warranty, which is where your problem is
