The ignition module or an ignition coil may fail causing the engine to misfire which can cause the Check Engine Light to illuminate or begin flashing.

    Have had this problem multiple times. 4 in the past 3 years. They replace the spark plugs for around $400 and call it good. I'm thinking there is more to it than that at this point.
