What is what does it mean when my engine light is blinking?

A blinking Check Engine Light is a serious warning sign. It indicates a severe engine misfire that could quickly damage the catalytic converter. A misfire means that one or more cylinders in your engine aren't firing properly.

Here's what it means in more detail:

• Catalytic Converter Damage: Unburnt fuel from the misfiring cylinder(s) is being dumped into the catalytic converter. This can cause the converter to overheat and melt down, requiring an expensive replacement.
• Stop Driving: If your check engine light is blinking, you should stop driving as soon as it is safe to do so. Continuing to drive can cause further damage.
• Seek Immediate Service: Have your vehicle towed to a qualified mechanic for diagnosis and repair. Don't delay. A blinking check engine light is not something to ignore.
• Possible Causes: Common causes of misfires include faulty spark plugs, ignition coils, fuel injectors, vacuum leaks, or a problem with the engine's computer.
