You may have a coil or plug that's going intermittent due to the engine frequency at that RPM causing it to temporarily fail. Is it a hard vibration, like missing on a cylinder?

It is not a real hard vib, its more like a rough idle vib but of course at higher rpms...im not really sure if it goes away after 3000 rpms or just the frenquency is so fast that it feels like it goes away, kinda like a washamachine when you first start a spin cycle and as it gets faster it kinda seems to smooth out..If it was a coil or plug, having the vehicross on a steep hill pointing down should not make it go away would it?
