Fox's cold car always shuts down for the first time when it is started in winter. What's the main problem?

Cause analysis: This problem is usually caused by too much carbon deposit on the accelerator or the throttle blade is stuck, because the second gear of the key door is the self-check gear of the system. During the self-inspection, the engine will give instructions to the throttle to make it move to prepare for starting. If there is too much carbon deposit or the blade is stuck, the throttle opening will be insufficient and the starting opening required by the engine computer will not be reached, and an alarm will be given to prompt the fault. If the engine does not catch fire at this time, it may cause the engine to flood the cylinder.

Coping strategy: If you can't start this problem, please adopt cylinder washing mode: manual gear suggestion: press the clutch pedal to the bottom, press the accelerator pedal to the bottom, start for 10 second, and release the key door when you get to the car. If there is no fire for 5 minutes at a time, repeat the operation; Automatic transmission suggestion: pedal the brake pedal to the bottom, pedal the accelerator pedal to the bottom, start 10 seconds, and release the key door when you get to the car. If there is no fire for 5 minutes at a time, repeat the operation.

Most people only know how to clean the throttle nozzle, but they don't know that the carbon deposit on the back of the valve is also the main reason why it is not easy to start the first photo.
