What causes a spark plug to melt?
A melted electrode on your spark plugs means that they’ve been running too hot for too long and could burn a hole through the top of a piston. A heavier, oily black deposit means that oil is being sucked down into the combustion chamber, likely via worn valve guides, guide seals or piston rings or a cracked piston.
How do you remove a melted spark plug?

If you have one or more bad Coil Packs, it’ll cause the acceleration of the Liberty to be weaker, and you’ll probably feel a jerking sensation.
