Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage ignition wires according to the firing order, and then secure the cover. Effects of faulty spark plugs: Damaged spark plugs can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in starting the engine, which affects the vehicle's normal operation. Severe erosion of the spark plug—such as scarring at the top, damage, or melted electrodes—indicates that the spark plug is ruined and should be replaced. Symptoms of faulty spark plugs in a car: Damaged spark plugs can lead to the following issues: difficulty starting the engine, reduced power, excessive exhaust emissions, and increased fuel consumption.
