What are the symptoms of a faulty spark plug in a Cruze?
1 Answers
The symptoms of a faulty spark plug in a Cruze are: 1. Difficulty starting or sudden stalling: Insufficient ignition energy fails to generate high voltage electricity, preventing the ignition of the air-fuel mixture in the cylinder, making the car unable to start. Even if it starts, it may suddenly stall; 2. Lack of power and excessive exhaust emissions: This leads to incomplete combustion of the air-fuel mixture in the engine, resulting in insufficient power, black smoke from the exhaust pipe, and the emission of harmful substances that have not been fully burned, causing excessive exhaust emissions. If the spark plug electrodes show signs of melting, erosion, rounding, or if the insulator has scars, cracks, or carbon deposits, it indicates that the spark plug is damaged. Although the car can still be driven for a short time, the spark plug should be replaced as soon as possible.
