Ford Expedition persistent engine light due to #2 cylinder misfire after extensive repairs on Ford Expedition

Some Ford Expedition owners report experiencing a persistent engine light due to a #2 cylinder misfire, which is a common concern that requires immediate attention. This misfire can trigger the check engine light, indicating underlying issues that need to be addressed. Various factors, such as faulty ignition coils, spark plugs, fuel injectors, or vacuum leaks, may lead to this cylinder misfire. Owners emphasize the importance of conducting diagnostic tests to identify the root cause, especially after extensive repairs. Additionally, a misfire can potentially cause catalyst damage, particularly if the check engine light is flashing, signaling a catalyst-damaging misfire. While some repairs might be manageable independently, many owners recommend seeking assistance from a qualified mechanic or dealer for persistent issues like this to prevent further damage and ensure the vehicle's proper functioning.
