When the Check Engine Light is flashing, it is telling you that the engine has a problem that may be causing damage to your catalytic converter assembly. The most likely problem is an engine misfiring from an ignition problem, such as a failed spark plug, plug wire, or coil problem. Some of these engines may also have problems with fuel injectors. I recommend having the Check Engine Light diagnosed by a certified mechanic, such as one from YourMechanic.
