Mikes to da rescue.....
It is most likely your AIS motor (Air Idle Speed). The exact same thing
you describe is what my Dak was doing. How many miles you got on it?
The AIS is on the very rear of the throttle body. Take it out with two
torx screws and clean it up real good with some throttle boddy cleaner,
and also clean the throttle body itself, take a shop rag (clean) and
clean out where the AIS piston goes. Put it back together and see if
that helps. If it helps it probably means that your AIS is going bad or
getting weak or slow to respond. This happend to mine about 7 months
ago and I cleaned it and it did fine for another month or so. I put in
a new AIS (I think it was about $40 or $50 and haven't had any problems
since.
Hope this helps ya! Keep us posted.
