Hi,
I saw your post on ford forum regarding your 2003 windstar. I just bought one with 41,000 miles, and am having the same exact problem with high rpms. When I start it, it seems to run very high 1500-2000 until it gets to operating temperature, then seems to calm down to 850 or so where its supposed to be. But then, if I stop and start again, even when engine fully warm and at operating temperature, it seems to do it again, and pulls me into interesection, however this time, maybe at 1100 rpm... Did you fix your problem ? Any help would be appreciated.
