What are the reasons for the Teana stalling automatically after starting?

[LeJames]

Teana stalling automatically after starting may be caused by the following reasons: Electrical circuit failure: It may be due to low-voltage power interruption during driving, causing the engine to stall. Solution: Mainly check the ignition and starter switches, as well as the fuse box. Low-voltage circuit short circuit: In this case, the engine stalls intermittently. Solution: Inspect the vehicle's low-voltage circuits. Throttle body failure: Excessive carbon buildup in the throttle body, idle speed control valve, intake manifold, intake valves, and combustion chamber can cause this issue. Carbon deposits make the intake pipe walls rough, creating vortices in these rough areas, which affect the intake efficiency and air-fuel mixture quality, leading to stalling. Solution: Replace the throttle body with a new one.
