If I recall, on these engines, the crank sensor controls ignition and injection up to around 2500 RPMs. After that, the cam sensor takes over. Is the check engine light on? Also, do you have access to a real time scanner that you can watch to see if there is a signal from the cam sensors?

It is also equipped with a rev limiter that will keep the RPM's from going too high when in Park or Neutral

See the guide below, it may help you figure out the issue

The car comes with a rev limiter from the factory. The oscillating sound is normal. What's the point of revving the engine in neutral though?
