WHOA if your engine light is flashing that is BAD! trust me I work on lots of vehicles. It flashes cause it wants to catch your attention right away, flashing means not only something s wrong but it can cause extreme damage and needs to be checked immediately. I would stop driving it and bring it in.

I have a mazda protege 2000 and the check engine light has been on for over a year now, i have never had a major breakdown but i have received alot of advise as to what the next thing to do would be. You need to take your car to a mechanic / dealer to run a computer diagnostic check on your engine, that's the only way to pinpoint what the problem is and depending on the severity of the issue you can plan your next move.

ok, if your check engine light is falshing it means the engine is misfiring (not firing on all cylinders for some reason). the reason it flashes instead of just lighting is because excessive misfiring causes the cat. conv. to heat up & eventually go bad which causes excess emissions.
You should check your plug wires & plugs. more than likely the plug wires are arcing causing a misfire. when u pull them out of the plug hole (while the engine is OFF!) look for traces of arcing.
you should see white burn marks or oil saturation from the valve cover gasket leaking into the hole. in either occurance the plug wire & plug should get replaced.
