Is It Necessary to Clean the Car's Intake Manifold?

[AustinDella]

Cleaning the car's intake manifold is necessary. The method is as follows: 1. Remove the fuel injectors, intake manifold, and any surrounding engine accessories that may obstruct the process; 2. Remove the ignition coils and spark plugs; 3. Inject the cleaning agent into the intake manifold and the spark plug installation points; 4. Use a vacuum tank to extract the cleaning fluid accumulated in each cylinder, then reassemble the engine in the reverse order of disassembly. The consequences of not cleaning the intake manifold include: 1. Inaccurate throttle opening; 2. Air with impurities entering the engine combustion chamber; 3. Poor vehicle acceleration and difficulty starting the vehicle; 4. Wear and tear on the throttle and choke plate.
