Iveco automatically shuts down when idling and can't start.

Hello, Li Shuo: According to what you said, the main reason is that the engine is unstable at idle speed due to too much carbon deposit in the throttle, which is easy to stall and difficult to start. There are too many carbon deposits and dirt in the surrounding intake port, and the cross-sectional area of the intake port changes, which leads to the control unit being unable to accurately control the idle intake volume, which leads to the mixture being too rich or too thin, which leads to abnormal combustion and even engine jitter after starting. At the same time, check the working state of the fuel injector, so it is recommended that you clean: 1 and excessive carbon deposit inside the engine. 2, check the gasoline pump oil pressure is too low. 3. Check whether there is leakage in the fuel injector. 4. Clean the throttle and idle motor. Check and repair according to the above five points. At the same time, it is best to check the carbon deposit with an endoscope in a conditional service station. Check one by one according to the above.
