Is it necessary to clean the fuel system and throttle body?

[SanMariana]

Cleaning is best determined based on the vehicle's condition. If the vehicle experiences sluggish acceleration, increased fuel consumption, or jerking movements, cleaning may be necessary. Below are specific details: 1. Functions: Cleaning removes carbon deposits and gum residues from the throttle body, unclogs the intake passage, improves fuel economy, reduces exhaust emissions, and ensures robust and stable engine operation. Cleaning the fuel system can enhance power output and help meet emission standards. 2. Cleaning intervals: (1) Throttle body should generally be cleaned every 10,000 kilometers. (2) Fuel system should typically be cleaned every 40,000 to 50,000 kilometers. 3. Throttle body: This is a controllable valve that regulates air intake into the engine, available in traditional cable-operated and electronic types. The incoming air mixes with gasoline in the intake manifold to form a combustible mixture for power generation. Connected to the air filter at the top and the engine block at the bottom, it's often referred to as the 'throat' of an automobile engine.
