Where is the throttle body installed?

The throttle body is installed between the intake manifold and the hose. It serves as a controllable valve regulating air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form combustible mixture for combustion. Symptoms of a faulty throttle body include: 1. Unstable engine idle speed with persistently high RPM; 2. Difficulty starting the engine; 3. Insufficient engine power, poor acceleration performance, and unstable operation; 4. Black smoke from the exhaust pipe; 5. Illuminated engine warning light. The cleaning procedure involves: 1. Turning off the ignition and disconnecting the battery negative terminal; 2. Removing the throttle cable, intake hose, and throttle body mounting screws in sequence; 3. Cleaning the throttle body with cleaner, using cotton swabs for hard-to-reach areas.
