Read in you haynes book about the idle control sensor. Does that sound like your idle problem? 10,000 miles is awful young to have these kind of problems. The car is not even broken in yet. Did it sit on a lot for a long time? It is 2001 and that is just over 1000 miles a year.

Could have a split plenum boot between the throttle body and intake causing a vacuum leak, this can be intermittent. Did they check for any codes, freeze frame info?
