Is it necessary to clean the intake manifold?

[VanAmelia]

It is necessary to clean the intake manifold, as there is currently no way to completely prevent carbon buildup. The only solution is to clean the intake manifold periodically. The hazards of not cleaning the intake manifold for a long time: 1. Carbon buildup, leading to engine shaking and reduced power output; 2. Causing engine cylinder scoring or seizure, making the car unable to start. Methods for cleaning the intake manifold: 1. Remove the fuel injectors, intake manifold, throttle body, and surrounding engine accessories; 2. Remove the ignition coils and spark plugs; 3. Inject cleaning agent into the intake manifold and spark plug holes, then scrub with a brush; 4. Use a vacuum tank to extract the cleaning fluid accumulated in each cylinder, and reassemble the engine in the reverse order of disassembly.
