A flashing check engine light on a 2018 Ford F-450 Super Duty indicates a serious misfire or condition that can harm the engine or emissions system if you continue driving.

Our technicians will prioritize a safe tow or immediate inspection, perform a full diagnostic scan, and isolate root causes — whether it’s a fuel system fault, injector or glow plug issue, or ignition-related event.
