Why Did the Car Ignition Coil Fail?
1 Answers
Car ignition coils fail due to the following reasons: 1. Excessive generator output, causing the ignition coil to overload and burn out; 2. Poor fuel quality; 3. Incorrect cylinder compression ratio; 4. Program failure in the computer board; 5. Unstable power supply voltage; 6. Abnormal resistance in the high-voltage wires; 7. Excessive primary current from the ignition controller leading to overheating of the ignition coil; 8. Malfunctioning ignition module. Symptoms of a failed ignition coil include: 1. The corresponding cylinder of the ignition coil will not operate, resulting in rough idling, weak acceleration, inability to increase fuel, and the check engine light turning on; 2. Power interruption during acceleration causing weak and shaky acceleration; 3. When a cylinder misfires, the air-fuel mixture in that cylinder will not ignite and will be expelled through the exhaust pipe, potentially clogging the catalytic converter's pores and causing catalytic converter failure.
