RPS=RPM?

So the RPM goes up and down when you are in N or when you are actually shifting between gears?

If you are talking about the car engaging, then it could be your clutch.

If the RPM just trips out, check out the fuses. Mine was doing this and found out that 1 fuse was blown on the kick panel, and another one on the engine bay.

^^ yeah, you might wanna try ceaning it. When there's too much buildup, the spindle gets stuck and causes a retarded idle.
