I got a 2001 Windstar, 3.8l, 200,000mi. The van rides great etc, but it has lately been doing this annoying thing when u start it up, the throttle cant seem to level out, it goes up and dad, and bucks until u get up to speed, and then it levels out and stops. Is this like a idle control sensor issue, or just a sign of tune up needed. Thanks

 

Yes, you need a tune up, and a gummed up MAF sensor can also be contributing. Check for vacuum leaks and replace any damaged hoses. Replace the PCV valve.
