Spark plugs and wires would be the least suspect with this problem. It would sound more of a fuel delivery/induction/high tension output problem. Take the car to a tune-up shop for diagnosis, or to a car parts store. Maybe they can get the fault codes for you. Check the warranty. It may even be best to take the car to the dealer for repair. I had a similar problem and it turned out to be the speed input sensor. No idea what this means but the dealer fixed it and it was covered under warranty so maybe it's just a common problem.
