If it is bad, just replace the one, not all....but be sure to check the wire connections as it may not be the coil. A loose spark plug wire is very common on the C6.

Totally
Could be just a loose spark plug wire, especially if the car has lower mileage.

Take a heat sensor gun and find the cylinder that is cold. They you can swap with another to see if it is the coil.
