What are the reasons for the difficulty in starting a Chery QQ?
1 Answers
The reasons for the difficulty in starting a Chery QQ may include: battery damage or low charge; abnormal air-fuel mixture or unstable power supply voltage in the ignition system. Battery damage: It needs to be sent to a repair shop for testing with professional computer equipment. Another possibility is low battery charge. If the car is often driven at low speeds with headlights, air conditioning, audio, and other devices frequently turned on, the battery consumption will be higher, potentially leading to low charge. It is recommended to drive at high speeds occasionally to allow the battery to fully charge. Abnormal air-fuel mixture: In this case, the engine usually cranks normally but fails to start. This phenomenon is generally caused by a dirty throttle valve, intake valve, or idle speed control valve. If the valves are too dirty, fuel may spray onto the back and be absorbed by carbon deposits, preventing the engine from starting. Cleaning these components usually solves the problem. Unstable power supply voltage in the ignition system: In winter, the engine's starting resistance increases, including insufficient battery power, leading to inadequate voltage in the entire ignition system. Additionally, sometimes after starting, if the accelerator pedal is not continuously pressed, the car may stall immediately. This is due to a dirty combination of the throttle body and fuel injectors. Slightly increasing the throttle may help, but if the difficulty in starting persists, the car should be sent to a repair shop for a thorough cleaning.
