I just purchased a aem short ram intake for my gf. She has a 02 auto rsx. I just installed it today with no problems, but when I reved the car up in park it would only go to around 5,000 rpm's. It sounds like it was hitting the rev limiter. I know that the rev limter isn't at 5grand, I have had it past there before.Anyone know what is wrong? please help me out.

Are you showing a check engine light or any other faults that you know of.
