If a coil-over-plug ignition coil fails on a F225NCA 4.2L V6, what will happen?

In a coil-over-plug ignition system, each cylinder is equipped with its own ignition coil that directly fires the spark plug. If a coil fails, the specific cylinder controlled by that coil will not receive the necessary spark to ignite the air-fuel mixture.

For the F225NCA 4.2L V6 engine, which has a total of six cylinders, if one of the ignition coils fails, it will result in the loss of ignition in that particular cylinder. Thus, the engine would continue running on the remaining five cylinders. The overall performance of the engine would likely decline, with a possible rough idle or reduced power output, but it would not stall completely or drop down to only three or four cylinders running.

This understanding confirms that the engine's ability to keep running is dependent on the functioning of the remaining coils and cylinders.
