Common Causes of a Blinking Check Engine Light
A blinking check engine light typically indicates a serious issue that requires immediate attention. Here are some of the most common causes:
- Engine Misfire: This occurs when one or more cylinders in the engine fail to ignite properly, leading to a rough running engine and jerking.

Addressing these issues promptly is essential to prevent further damage to your vehicle. Ignoring a blinking check engine light can lead to more severe problems and costly repairs.
