Climing Idle

[Sarumatix]

last week my idle just shot up to 1500. I fiddled around with the idle screw and it seemed to settle down.. however whenever I drive the car it slowly increases the idle speed each time I pull up at some lights. Any ideas? A mate mentioned that funnyness with a lack of Aircon can do this?

If I unplug the aac nothing much happens, if I wind the idle control screw down (it's now at the bottom) the idle drops but doesn't get below 1100. If I apply any (slightly) pressure on the throttle linkage the idle drops down.

even with idle fully screwed in it has climbed back up to 1500

try removing the entire AAC valve and giving it a good clean with throttle body cleaner / brake cleaner

then put it back on and screw the idle screw in about half way

then plug the AAC back in and see how it is

while you're there, give the AFM a clean with brake cleaner..

cheers,
