What Are the Symptoms of Aging Car Spark Plugs?
1 Answers
The symptoms of aging car spark plugs include: 1. Increased deposits inside the spark plug; 2. Melting or burning of the electrodes; 3. Malfunction of the ignition system; 4. Reduced power and sluggish acceleration; 5. Severe idle vibration; 6. Difficulty starting or sudden engine stalling. The effects of aging spark plugs: 1. Lower power output, reduced shunt resistance, unstable engine operation, leading to weak throttle response; 2. Significant car vibration during idle; 3. Increased exhaust emissions and higher fuel consumption. The function of car spark plugs is to receive high-voltage electricity from the ignition system, create an electric spark by ionizing the air between the electrodes, and ignite the air-fuel mixture in the cylinder.
