What Causes Engine Fuel Cut-off?

[SawyerAnn]

Reasons for engine fuel cut-off: 1. If it occurs during normal driving without acceleration or deceleration, it may be due to a fault caused by decreased resistance or short circuit in the ignition coil at high temperatures, leading to a drop in secondary voltage. 2. Poor contact in the clutch switch. It is recommended to check whether there is excessive carbon buildup in the engine throttle, fuel injector, intake tract, valves, and combustion chamber, as excessive carbon deposits can cause this issue. Timely cleaning of the combustion chamber is essential. Additional information about engine fuel cut-off: Engine fuel cut-off refers to the situation where the vehicle's computer automatically stops supplying fuel to the engine when the engine speed reaches a certain threshold, such as 8000 RPM, to prevent the engine speed from exceeding the limit. This is a special design by manufacturers to protect the engine.
