What Could Be the Reason for Feeling Less Power After Changing Spark Plugs?
1 Answers
The reasons for feeling less power after changing spark plugs may include: The spark plugs were not tightened properly; The replaced spark plugs are of the wrong model; There is an issue with the ignition coil. Effects of damaged spark plugs: If the spark plugs are damaged, it can directly cause various problems such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant issue is difficulty in ignition, affecting the normal use of the vehicle. Severe erosion of the spark plugs, scarring at the top, damage, or melting and erosion of the electrodes indicate that the spark plugs are damaged and should be replaced. How to determine if spark plugs are damaged: Remove the spark plugs and observe their appearance to assess their condition. Normal spark plugs have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plugs are covered in oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, showing signs such as scarring, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or that the mixture is too rich, with oil seeping up.
