Carbon tracking on spark plugs may cause misfires on Dodge Neon

The engine may develop misfires when accelerating up a grade or when carrying a heavy load. This can be from carbon tracking that has developed on the spark plugs causing the plug to not fire (misfire). The engine will run roughly and lose power.
