Ignition coils should be replaced every 100,000 kilometers. The replacement method for ignition coils is: 1. Open the ignition coil cover on top of the engine and use a pentagonal wrench to remove the ignition coil fixing screws; 2. Disconnect the ignition coil power plug, gently pry it up with a screwdriver, and remove the ignition coil; 3. Install the new ignition coil, tighten the screws, and reconnect the power plug. Symptoms of a damaged ignition coil include: 1. The corresponding cylinder of the ignition coil will not work, causing idle vibration, weak throttle response, inability to accelerate, and the fault light turning on; 2. Power interruption during acceleration causing weak acceleration and vibration; 3. When a cylinder misfires, the gasoline and air mixture in that cylinder cannot ignite and will be expelled through the exhaust pipe, leading to clogging of the three-way catalytic converter pores and resulting in three-way catalytic converter failure.
