vy ls1 high idle!! please help.

[Webby6829]

Hey similar issue, need help... 2002 VY SS commodore ute, when i first start the car it revs up high and slowly comes back down after 30secs then it idles down and when i put it in reverse it does the same thing. I have replaced the idle control valve and throttle positioner as well. I think they need to be programmed, have tried a couple suggestions (the turn on, turn off remove fuse etc etc etc) nothings worked.
