What are the symptoms of aging ignition coils?
1 Answers
Ignition coil aging manifests as follows: Engine vibration: During operation, the engine may exhibit intermittent shaking, accompanied by symptoms such as sluggish acceleration. Increased fuel consumption and reduced power: As the spark plug's firing capability weakens, the combustion of the air-fuel mixture in the engine becomes incomplete, leading to adverse effects like increased fuel consumption and decreased power. Excessive carbon buildup: Weakened spark plug firing capability results in incomplete combustion of the air-fuel mixture. This incomplete combustion produces a carbonaceous deposit called carbon buildup, and black smoke may also emerge from the vehicle's exhaust pipe.
