Answers :

The most probable cause for high idle on the 3.1 is.the idle air control motor, this is preset. the thing to do is to remove and clean it out if carbon built up is on it, also clean where it mounts to engine. when cleaning do not soak it in any kind of liquid. us a old tooth brush or sorts to clean around valve on end of motor. do not push in on valve as it will lose its setting. also if you had to remove the throttle cables, make sure they are not binding somewhere. on my 2000 3.1 it is 1 and 1/8 from body to tip of valve. good luck!
