I had asked this question before when I first bought this car last year but it's still bugging me so I'll ask it again. When I first start my car ('99 Duratech) after it has been sitting overnight or at least 7-8 hours the initial idle speed varies from 1800-2300 rpms. After about 20-25 seconds the engine eventually settles down to around 1000 rpms. I have been told this is normal for this car. My wife's '01 Windstar with the 3.8 somewhat does the same thing but the startup idle only hits about 1400-1500 rpms. I use a full synthetic oil and I don't always have the luxury of parking it in the heated garage at work, although it's always in the garage at home. Does this situation seem correct for the 24v engine? Having the motor rev over 2000 when it's below zero makes me cringe.
