How to Determine When Spark Plugs Need Replacement

[LeMason]

Methods to determine when spark plugs need replacement: 1. Difficulty starting the car: If the spark plugs malfunction, the car won't start, and they need to be replaced as soon as possible; 2. Frequent shaking while driving: Indicates severe carbon buildup on the spark plugs, requiring prompt replacement; 3. Weak climbing power: Excessive carbon buildup on the spark plugs leads to incomplete fuel combustion, reducing engine performance; 4. Increased fuel consumption: Abnormal spark plugs will cause a noticeable rise in fuel consumption. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder.
