What are the symptoms of a faulty ignition wire?

[LilyFitz]

Symptoms of a damaged ignition wire are as follows: 1. Insufficient power: The car lacks strength when going uphill, and the engine noise is noticeably louder. 2. Jerky acceleration: Occasionally feels a jerk when accelerating above 80 km/h, with occasional jerks at speeds around 80 and between 100-120 km/h, resulting in an unsteady acceleration. 3. Increased fuel consumption: Noticeably higher fuel usage, with black soot at the exhaust pipe outlet. This can cause mild or severe gear shifting issues. Sometimes the car fails to start and requires a bit of throttle to start. Note: When the car reaches a certain mileage, spark plugs will develop carbon deposits, and the electrode gap will increase. Carbon deposits will increase engine fuel consumption, and an increased spark plug gap can cause difficulty in starting.
