97 jeep TJ with Straight six 4.0L... Hope in for lunch fire it up and 2500 RPMs.. peddle not sticking and throttle body good shape and not sticking and no slack in cable and spring is strong... after a minuet or so it stays at about 1700... What Could It be? IAC? maybe vacuum hose? i didn't see any off but i will double check.. intake boot/tube looks good.. sensor problems? im at work so at cant be playing detective yet but maybe i can get a good idea before then.. thanks
