12 The spark plug of an eight-year-old car with more than 60,000 kilometers has not been replaced. When replacing the spark plug myself, the ignition coil rubber sleeve broke due to repeated pulling out of it many times. After installing the spark plug, there was an occasional fire when starting the engine, which caused the engine to occasionally shake and shake when accelerating. I bought a new ignition coil and put it on, but it still shook. Finally, I found out that it was caused by the broken rubber sleeves of two ignition coil. I repaired the ignition coil myself and bought 4 rubber sleeves and accessories from Taobao. Solve the problem of occasional engine shaking and accelerate shaking, and the fault is perfectly eliminated. After repairing, an ignition coil is left for backup.
