What this warning means
Misfire-related catalyst/engine damage may be possible.
What you may see: MIL flashes while the engine is running.
Equipment and scope: Only if equipped; verify exact model-year owner manual.
First checks while safely parked
- When parked, record the exact symbol, color, flashing pattern and message.
- Use the selected vehicle manual before interpreting a similar-looking symbol.
When to get professional help
- Use a technician with support for the affected system when the fault persists.
What this warning does not prove
- A cylinder code identifies a reported cylinder, not a proven bad coil.
- Do not swap coils using a generic cylinder-location diagram.
- Do not reproduce a severe misfire on a test drive.
The checklist is an editorial reading of the cited sources, not an OEM repair procedure. A warning name alone does not identify a failed component.
Questions for a qualified shop
- Do ignition, fuel delivery, air leaks or mechanical compression explain the affected cylinders?
- Does an exact-engine compression/leak-down or ignition waveform test distinguish the cause?
- For Ford 25-2293, does recorded ECT meet the documented temperature branch?
