1998 expedition Engine light on blinks while driving has heavy hesitation wasting fuel?
Borrow, rent or buy a computer diagnostic scanner from your local auto parts retailer. If the light is blinking, the computer is trying to tell you what's wrong. You need to connect the diagnostic scanner to find out what's wrong. Many auto parts retailers will even help you figure out what's wrong by assisting you with the connection and reading the results. It could be as simple as a faulty oxygen sensor or throttle position sensor, but it could also be a lot more complex than that. Good luck.
