Why does my 2001 Ford Ranger XLT throttle back at 3200 RPM when in park but does fine on the road?

The powertrain control module cuts back on the fuel to limit RPM to prevent damage to the engine when it is in gear - at a much higher RPM , but also cuts back on the fuel at a much lower RPM when not in gear and there is no load on the engine
