Spark plug wires are a critical link in a vehicle's electrical system. Responsible for transporting electrical power from a vehicle's ignition system to its engine spark plugs, spark plug wires need to function properly to ensure normal engine operation. When spark plugs wires fail, a host of engine problems can result.

Symptoms/Signs of a worn spark plug cable:

Rough Engine Idle - Bad spark plugs wires can inhibit the normal flow of electrical current that reaches a vehicle's spark plugs, which can cause a rough, erratic engine idle.

Engine Miss Firing - Normally occurs as the result of erratic or incomplete engine combustion

Engine Hesitation - Mostly apparent during acceleration, is a condition that often results from either abnormal fuel flow to an engine or abnormal electrical conduction to a vehicle's spark plugs

Reduced Engine Power - Any abnormalities in its spark plugs or spark plug wires, can negatively affect spark plug firing, which will influence engine combustion and engine power

Engine Surging - If the wires have cracks or breaks in their outside insulation, a condition that can create significant electrical resistance and lead to abnormal or completely stopped electrical flow to a vehicle's spark plugs.
