What are the symptoms of a leaking cylinder wire?
2 Answers
Cylinder wire leakage can cause symptoms such as engine shaking, unstable idle, and weak acceleration in the engine. There are many reasons that can lead to weak acceleration, shaking, and unstable idle in the engine, and cylinder wire leakage is just one of them. Excessive carbon buildup in areas such as the throttle body, idle motor, intake valve, intake pipe, combustion chamber, spark plugs, and fuel injectors can also cause such faults. The cylinder wire and its quantity are as follows: 1. Cylinder wire, also known as high-voltage wire: As the name suggests, the high-voltage wire is responsible for transmitting the high-voltage current generated by the high-voltage coil to the spark plug. A set of high-quality high-voltage wires must have minimal current loss and avoid electromagnetic interference generated during the high-voltage transmission process. 2. The number of cylinder wires is the same as the number of engine cylinders: With technological advancements, many cars now no longer have cylinder wires. The cylinder wire and ignition coil are integrated into one, with one ignition coil per cylinder, greatly reducing the size and providing more convenient conditions for independent ignition per cylinder.
As someone who frequently works on car repairs, I've seen too many cases of leaking spark plug wires. When a spark plug wire leaks, the engine shakes violently, especially at low speeds or idle, causing the entire car to wobble. Starting the engine becomes difficult, often requiring multiple attempts before it fires up. Acceleration is sluggish, and the car struggles to climb hills as if it's running on empty. Worse yet, the engine compartment sometimes emits crackling sounds, and you might even smell something burning, particularly noticeable in humid or rainy weather—moisture exacerbates the leakage. Fuel consumption also skyrockets, wasting gas and polluting the environment. If not addressed promptly, the spark plugs can easily burn out, and other components of the ignition system may suffer collateral damage. I recommend using a multimeter to measure resistance early on, locate the faulty wire, and replace it to avoid triggering a check engine light and costly repairs. Safety first—delaying repairs risks stalling on the highway, which is dangerous.
