What is the throttle diameter of Nazhijie s5?

According to your brief description of vehicle failure, this situation belongs to the phenomenon of poor engine working condition, and the maintenance methods are mainly divided into the following points:

1, engine mechanical inspection, that is, the balance test of each cylinder of the engine, whether there is uneven work of each cylinder, such as cylinder pressure value, air leakage in the intake system, etc.

2. Ignition performance: check the resistance of high-voltage line, and judge whether the cylinder line resistance is too large or the performance is degraded by measurement and visual inspection. If the high-voltage line has poor contact or electrical corrosion, it is recommended to replace it.

3. Sensor data analysis: use the maintenance diagnostic instrument to check the engine data flow and detect the water temperature sensor signal to see whether its resistance value is within the standard range or changes with the engine temperature, otherwise it will bring an error signal to the engine control unit, thus causing the above phenomenon.

To sum up, I suggest you go to a repair shop for inspection or repair, which is a common condition of engines and easy to eliminate.
