If your check engine light kicks on, I would either get an ODB 2 diag unit and plug it in and check for an error code, or I would let a shop do it.
On 1998 and 99 windstars a flashing MIL (check engine light) means that the computer has detected one or more misfiring cylinders. You will need to connect an OBDII compliant scanner to the datalink port under the dash on the drivers side to scan the computers trouble codes and determine which cylinders are misfiring.
That's the computer's way of saying "read my codes". You can borrow, rent or buy a code scanner from most auto parts retailers. Any time the light comes on like that it's indicating that the computer has detected a "fault code" meaning that something is wrong. The computer can tell you exactly what it means. There really is no way to guess and be anywhere near accurate, but probabilities are: oxygen sensor, EGR valve, map/maf sensor, misfire or any of a number of potential problems. The computer is trying to give you the best possible fuel economy and minimize emissions. If the computer has detected a fault it will be unable to be as effective.
