There are multiple causes of high idle on this application. They include throttle cable out of adjustment, IAC problems, evaporative emission failure, and vacuum leaks (among others). This is a critical safety issue due to the possibility of uncontrolled throttle and must be diagnosed and serviced by qualified mechanic.
