Clean it now! its well worth it.
Background:
As the weather cooled down, my idle started to stick at 2krpms. Also after long trips, when stopping to pay tolls and whatnot, my car would stall out. I thought that was the extent of the problems.
How to: Sorry no pics. T5 ng900.
Remove plastic engine cover.
unscrew hoseclamps on either side.
AIC valve should be soup can sized thing just to the left of throttle body.
Peal hoses of either end.
Remove electrical connection, just squeze fitting and slide off.
Pull AIC and rubber bushing straight up.
Clean out with carb cleaner, and give a small shot of oil I used Penetrating oil.
Reinstall.
Not only did this cure my cold high idle off throttle, The car has never ran smoother. It doesn't even feel like its running at stops, and this is with a catless dp and saabsport. It also feels like it shifts better, probably because the rpms drop faster with the clutch in.
Seriosly if you haven't taken the time, its worth it. Its only a 30min job, and you only need a flathead screwdriver and some carb cleaner.
