What Causes Frequent Spark Plug Flooding?

[StMalia]

The reasons for frequent spark plug flooding include: weak spark, electrical leakage, abnormal ignition from the ignition system, or malfunctioning ignition coils. It is essential to inspect and replace the spark plugs promptly. Steps for replacing spark plugs: Open the engine hood, remove the plastic engine cover, and detach the high-voltage distributor wires. 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 debris such as leaves or dust around the area and ensure it is thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to fully tighten it. Reinstall the high-voltage distributor wires in the correct firing order and secure the cover. Damaged spark plugs can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty starting the engine, which affects normal vehicle operation. Severe spark plug erosion—indicated by scarring, electrode damage, or melting—means the spark plug is ruined and should be replaced immediately.
