A flashing Malfunction Indicator Light (MIL) serves as a critical alert for drivers, indicating a severe engine misfire. When this occurs, it suggests that the engine is not operating smoothly and is experiencing a failure in its normal combustion process. This condition can lead to increased emissions, potential damage to the catalytic converter, and reduced fuel efficiency.

The flashing light is a prompt for immediate attention, as it signifies that the vehicle’s onboard diagnostic system has detected a significant issue that could affect both vehicle performance and environmental regulations. It's important for drivers to pull over safely and address the issue as soon as possible to prevent further damage and comply with emission standards.

Understanding the significance of a flashing MIL is essential for maintaining vehicle health and ensuring compliance with emissions regulations, especially in regions that monitor vehicle emissions closely, like Utah County.
