Check Engine Light Flashing

A flashing check engine light on a 2016 Ford Focus RS signals an active misfire or condition that can allow unburned fuel into the exhaust system, risking catalytic converter damage and further engine harm. This state requires immediate attention: slow down, avoid sustained high RPMs, and bring the vehicle to Herb Chambers Ford of Braintree right away. Our certified technicians use factory diagnostic tools to capture live data, identify misfire sources—ignition coils, spark plugs, fuel delivery, or sensors—and recommend repairs that protect your engine and emissions system. We explain the issue in plain terms, provide transparent estimates, and discuss warranty implications; remember, warranty-covered repairs must be completed at a certified dealership to remain valid.
