About ignition / high tension leads:
When you turn the keys in your car, the energy is transferred from your car’s battery to your ignition system where the spark plugs ignite the air/fuel mixture in the engine. In many car petrol engines, the high tension leads (also referred to as spark plug wires or ignition leads) connect to each spark plug in your car’s ignition system. The high tension leads are responsible for the transfer of high-voltage electricity from the spark plugs to the rest of your ignition system.
Ignition leads are made out of a durable material designed to withstand high voltages and temperatures. However, they can sometimes become worn and damaged. Any problems with the ignition leads can make it difficult for your ignition system to keep the air/fuel mixture burning in your engine. When this happens, an ignition high tension lead replacement may be necessary to fix the improper burning conditions in your engine.

Symptoms of damaged ignition leads:
Damaged ignition leads, also known as spark plug wires or ignition cables, can cause various symptoms in a vehicle’s performance. Here are some common signs that may indicate ignition lead damage:
Car not burning fuel correctly – Faulty ignition cables can prevent the spark plugs from sparking the engine’s air/fuel mixture when they need to. This can result in a decrease in engine performance. This can cause the following symptoms to occur:
- Limited speed due to a loss of power.
- Increased fuel consumption due to fuel not burning correctly.
- Increased misfires due to fuel not burning correctly.
- Increased exhaust emissions including harmful greenhouse gases
Engine stalling – In more severe cases of damaged ignition leads, the engine may stall while you are driving. This is due to the engine being unable to generate enough power as it may not be running on all engine cylinders.
Check engine light on – Faulty ignition leads can prevent fuel from burning correctly. The engine light will activate if improper fuel burning conditions are detected.

Car not starting at all – Severe damage to one or more ignition leads can prevent the car from starting at all. This happens when the damaged lead is preventing any electrical energy from reaching the spark plugs.
Engine hesitating – When you press the accelerator pedal, a damaged ignition lead can cause the engine to hesitate or stumble before accelerating smoothly. This hesitation is usually more pronounced during quick acceleration or under heavy load.
Misfiring engine – One of the primary symptoms of damaged ignition leads is engine misfires. You may notice a rough-running engine or a noticeable lack of power during acceleration. The misfires can be intermittent or consistent, depending on the severity of the damage.
Rough idling – Damaged ignition leads can lead to an uneven idle, where the engine may feel shaky or unstable when the vehicle is at a stop. The rough idle can be accompanied by engine vibrations.
