Does the Dashboard Display Spark Plug Failure?

[DelAiden]

The dashboard will display spark plug failure. The causes of spark plug failure include burnt spark plugs or improper spark plug gaps, which require timely replacement. If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal use of the vehicle. Severe spark plug erosion, such as scarring at the top, damage, or electrode melting, indicates that the spark plug is already damaged and should be replaced. Steps to replace the spark plug: Open the engine hood, lift the plastic cover of the engine, remove the high-voltage distributor 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 external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the ignition order and secure the cover plate.
