I just bought a 2003 Subaru Outback with 208,000 miles. This car has been very well maintained. I am however having an intermittent idling issue. 90% or more of the time the car runs, drives, and idles perfectly. Intermittently - only about 10% of the time or less, the cars does not want to idle. It does still run and drive fine even when experiencing this condition (it just takes two feet to keep it running while stopped). Also for no apparent reason it will "fix itself" and will idle normally. No set pattern, temperature, condition, etc... Again: VERY INTERMITTENT. Any ideas/help? This is my first Subaru - so far, I REALLY like the car.
