What do you mean by this exactly? Are you doing this in park or neutral? The gen II has electronic throttle control. There is no physical connection between the gas pedal and the throttle. The PCM takes the gas pedal position as an indication of how much power the driver wants. It then uses the throttle, the transmission gear, and other engine controls to accomplish what the driver wants. In park or neutral, the system goes into a diagnostic mode that gives very slow throttle response and limits engine RPM.
