While driving, there was a loud explosion, then engine was running rough and loud. Mechanic stated that due to a faulty design, the #7 spark plug had been shot from the engine, damagine the ignition coil and allowing fuel to spray from the injectors onto the now loose spark plug. Mechanic stated I was lucky this did not result in an engine fire. Engine is Ford 5.4L V8. Mechanic explained that the design of the engine means that the aluminum heads have approx. Half as many threads as a normal spark plug, meaning that this is a frequent occurrence and Ford is aware of the fire risk but has chosen not to address.
