That is a design feature. The Contique ATX has a neutral rev limiter set at about 4,000 RPM to keep you from blowing up the engine from bliping the throttle. The computer shuts down the fuel injectors. You also have an in gear rev limiter at about 6800 RPM and a speed limiter at about 118 MPH.
If you find the 4000 RPM limiter bothersom, try explaining the 3000 RPM limiter to a Lincoln LS owner.
