What are the symptoms of damaged engine high-voltage wires?
1 Answers
The symptoms of damaged car high-voltage wires include the spark plug releasing a dim yellow and insufficiently energetic spark, which fails to properly ignite the air-fuel mixture, prevents the spark plug electrodes from releasing sparks, and leads to issues such as misfiring due to unburned mixture. Hazards of engine misfiring: Engine misfiring results in reduced engine power, increased fuel consumption, and noticeable vibrations and noise. Prolonged operation of an engine cylinder that only injects fuel without ignition can also cause gasoline flooding in the cylinder. Manifestations of ignition coil failure: At idle, the vehicle body shakes noticeably; while driving, when the RPM is below 2500, the body exhibits significant shaking and weak acceleration; once the RPM exceeds 2500, the shaking sensation disappears. Opening the engine hood and observing the running engine reveals obvious engine vibrations.
