if the car is running really rich in open loop (first 38 seconds or so) it will rev higher. That sounds more like an air leak though.

My dad's car used to do this whenever it wanted and it was because we had the crank case ventilating and it was confusing the computer. It was blown though so i don't know if it would do the same thing on a N/A motor.
