• Remove the ignition coil cover if applicable.
• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the spark plug from cylinder 2 using a spark plug socket.
• Inspect the spark plug for wear, carbon buildup, or damage. Replace if necessary.
• Install a new spark plug, ensuring it is gapped correctly as per manufacturer specifications (typically around 0.028-0.032 inches).
