Root Cause

The insulation inside the pencil coil breaks down due to engine heat. The spark then jumps to the cylinder head instead of crossing the spark plug gap.

How To Fix

Read OBD codes to identify which cylinder is misfiring (e.g., P0302 = Cyl 2).
Swap the coil pack to another cylinder and re-read codes to confirm the coil is at fault.
Replace coil pack (£30-60 each).
Advised to replace spark plugs at the same time.
