What could be wrong if the check engine light blinks?

If the check engine light (also called the malfunction indicator lamp or MIL) is blinking rapidly or flashing, this can indicate a *severe engine misfire*.

A misfire means the fuel/air mixture is not igniting properly in one or more cylinders. This can cause various problems, including:

- Engine damage

- Poor performance

- Increased emissions

- Rough idling

If the check engine light is blinking, it's essential to have your vehicle checked out by a mechanic as soon as possible.
