Hesitation

New 2004 Camry XLE. Great car, <500 miles so far, but I seem to detect that the drive is not smooth, especially at lower speeds. It's as if the car is fighting the engine (or computer), and the RPM drops slightly and then returns. Hard to describe, maybe I'm just not used to something. Does this sound like a computer or other problem that I need to have looked at, or will it go away or I just get used to it?

with less than 500 miles on the clock, take that bitch back to the dealership and ask them.

I agree with the above.
If it were older, I'd say clean the TB, clean the air filter, give it a tune-up, change the fuel filter and so on. Considering it's age though (or there a lack of), you shouldn't have any of those problems.
