High idle

[Stormbird]

There is a hole inside the throttle body...spray carb cleaner into the hole to get to the IAC valve. I had the same problem and it worked on mine. It was a major improvement at least. I also disconnected the battery for an hour and reconnected it to reset the computer. I want to remove the IAC valve and give it a proper cleaning or replace it but I don't have a short enough screwdriver to get at it lol. Let us know what it turned out to be as many people have the same issue.

And thanks for the input DOAX,,,i used your advice on my car and it seemed to work ok.

Goodmorning all,high idle has been sorted out,they put a new iac but stiill it was the same.they then put a new intake manifold kit.the problem is now when you start it,it just dies it doesn't idle,it doesn't do it all the time.other times you will start it ansd it will idle.and drive fine and the all of a sudden when you gear down to stop at robot or so it again won't idle.I connected my elm 327 with my laptop using scanmaster but I don't get any faultcodes.any help will be highly appreciated.
