What Causes a New Energy Vehicle to Stall Automatically?

[MorganRose]

Specific explanations are as follows: 1. Insufficient Air Intake: The engine stalls automatically at idle. In most cases, this is due to issues with the throttle body or idle air control valve. Severe carbon buildup or component damage in these areas can trigger this fault, with insufficient air intake being the primary cause. Additionally, the air filter, mass airflow sensor, intake pressure sensor, and throttle position sensor should also be thoroughly inspected. 2. Spark Plugs and Ignition Coils: The problem may lie with the spark plugs or ignition coils. Poor spark plug ignition quality or damaged ignition coils can be diagnosed through ignition tests, but this should be performed by professional automotive technicians—do not attempt to resolve it yourself. 3. Poor Engine Idling: Incorrect idling speed, either too low or too high, rough idling, or unstable idle conditions. The construction and principles of fuel-injected engines differ significantly from carburetor engines, making the causes of poor idling numerous and complex, thereby increasing the difficulty of fault diagnosis and troubleshooting.
