Check engine light blinking and idles rough on a 2000 ford windstar?

ANSWER: Sounds like it might need a tune up at the very least. Take it to AUTOZONE or most any aftermarket auto parts supplier, they can hook up a reader to your car and find out what code is being generated which will tell you almost exactly what is wrong. Most places are glad to do this for free since they are hoping you will buy your repair parts there.
