The effects of spark plug leakage include: 1. Engine power loss; 2. Unstable idle speed; 3. Engine stalling at high speeds; 4. Increased fuel consumption; 5. Engine failure to start; 6. Spark plug malfunction; 7. Engine damage. Other common spark plug faults include: 1. Spark plug leakage; 2. Black deposits on the spark plug electrodes; 3. Fractured insulator tip; 4. Oil fouling on the spark plug; 5. Spark plug erosion; 6. Excessive spark plug gap. The function of the spark plug is to discharge the high-voltage pulse sent by the high-voltage wire, breaking down the air between the two electrodes to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder.

Spark plug leakage can cause significant issues. I remember a friend's car always felt sluggish with slow acceleration, and it turned out to be due to leakage. It reduces cylinder pressure, destabilizes ignition, and can cause engine shaking or even stalling. When driving, the car consumes much more fuel, emptying the tank quickly, and emits excessive pollutants, harming the environment. If left untreated, leakage can damage the spark plug or other components, like warping the cylinder head from uneven heating, leading to costly repairs. Worse, engine overheating increases the risk of spontaneous combustion, making driving unsafe. I recommend replacing spark plugs regularly and checking them every two to three years to avoid such problems.

Spark plug leakage is really frustrating. I think driving a car should be smooth and powerful, but once there's a leak, everything changes. The power output takes a direct hit, acceleration feels like a snail climbing a hill, and it's especially noticeable when drifting at high speeds. Fuel consumption skyrockets, emptying your wallet, and you often smell pungent exhaust fumes. I've seen a neighbor's car stall on the roadside because of this, nearly causing an accident. If not fixed in time, it can also damage the ignition coil and other parts, costing hundreds of dollars for replacements. So, it's important to regularly check the condition of the spark plugs. If you notice any abnormal noises or shaking, take it to a professional shop immediately—don't delay.

Spark plug leakage can have serious consequences. It causes insufficient pressure in the engine, reduces combustion efficiency, weakens the vehicle's power, and increases fuel consumption. The lesson I've learned is that prolonged neglect can lead to overheating and deformation of components, raising repair costs, and even causing safety hazards such as breakdowns during driving. Regular inspection is crucial.

Spark plug leakage is no trivial matter. I've found it directly affects engine performance, weakening power output and making it difficult to accelerate when stepping on the gas. Fuel consumption soars, costing significantly more per kilometer. Over time, uneven cylinder heating can cause damage, and replacing parts is expensive. Safety-wise, it's even worse – engine overheating and stalling on the road is extremely dangerous. I recommend getting it checked and repaired at the first sign of trouble to save both hassle and money.
