If the vehicle is only driven in urban areas, the air filter may not get clogged. However, after driving on dusty roads, special attention should be paid to cleaning the air filter. 2. Throttle Sludge: The formation of sludge in the throttle can result from various factors, such as carbon deposits from fuel combustion exhaust accumulating in the throttle, or impurities not filtered by the air filter remaining there. Excessive sludge can cause air intake resistance, leading to increased fuel consumption.
