What Causes Sudden Throttle Failure?

[LeJoanna]

Sudden throttle damage can occur due to the following reasons: 1. Unstable engine idle or no idle: The engine idle is unstable, high idle persists without dropping, and the engine is difficult to start, especially during cold starts. 2. Insufficient power: The engine is hard to start. Once started, the engine lacks power, has poor acceleration performance, and operates unstably. 3. Black smoke from the exhaust pipe: The car's exhaust pipe emits black smoke, and fuel consumption increases. 4. Throttle: It is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to produce work. Connected above to the air filter and below to the engine block, it is often referred to as the throat of the car engine.
