How to Determine Throttle Leakage and Power Loss?

[McNora]

Methods to determine throttle leakage: 1. Check for poor fuel combustion: When the engine is running, if the throttle is leaking, it will manifest as insufficient cylinder compression, poor combustion, regular emission of black or white smoke from the exhaust, increased fuel consumption, and reduced power. 2. Check if the intake manifold is overheating: If accompanied by an overheating intake manifold, a hissing sound in the central intake pipe, or even reverse airflow in the air filter, it indicates severe throttle leakage. 3. Check throttle cleanliness: The throttle is a controllable valve that regulates air intake into the engine, available in two types: traditional cable-operated and electronic throttle. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. Connected to the air filter at the top and the engine block at the bottom, it is often referred to as the throat of the car engine. The responsiveness of the car's acceleration is closely related to the cleanliness of the throttle.
