1997 Sebring Coupe-Help

If you mean the wire end of the plug (as opposed to the spark side which is inside the engine combustion chamber so should be exposed to vaporized gas there), then this is a serious problem and needs to be fixed ASAP or risk a fire. I'd guess the only way fuel could get there is from a leaking fuel rail. As I recall, there was a manufacturer recall on many Chryslers covering many years. I do not know if this vehicle was covered or if the mandatory service was performed. I'd suggest you contact the dealer and give them the VIN asking them to see if any recalls are outstanding. If I understand your observations correctly, then do not drive the car in this condition.
