a flashing check engine light indicates a misfire that could damage the catalytic converter. The vehicle may need to be hooked up to a scan tool to troubleshoot your misfire.

Have your codes read. This will lead you to to your issue. Your local auto parts store will do this for free. Also I do not advice driving with a flashing check engine light.
