Most common problems, symptoms & fixes for the FSJB engine.
Engine FSJB in the Ford Fiesta 1.1 Duratec (2019–2023) is generally reliable but may experience common issues like rough idling, misfires, or reduced power due to spark plug wear or ignition coil faults. Diagnosis involves checking for fault codes with an OBD-II scanner and inspecting spark plugs and coils. Preventive maintenance includes regular oil changes, using quality fuel, and timely replacement of ignition components. If misfires occur, replacing spark plugs and coils usually resolves the problem. Also, ensure the air filter is clean to maintain proper airflow. Addressing these promptly helps maintain engine performance and longevity.
