Various problems affect spark plugs. This can be heat and cracks in coil boots, or the parts that connect the plugs to coils, causing misfires, poor acceleration, and rough starts. Related issues are abrasion, heat, and vibration damage in the Spark Plug Ignition Cables, meaning plugs don't get enough voltage for efficient ignition. Coils, plugs, and Replacement Spark Plugs are relatively easy to diagnose and inexpensive to fix.
