The high idle is an indication of vacuum leak, however, if it idled down then the reason has to be a part in the engine control system. Check: idle control, EGR (if equipped), and have ECM scanned for trouble codes (be careful: if you get a code indicating a bad Oxygen sensor this is just a result of too much gas resulting from high idle or vacuum leak). Please click on "Mark helpful" if you're happy with the respond. Good luck :-)
