What happens when there is insufficient engine air intake?

[Valeria]

Insufficient engine air intake manifests as symptoms of too little air and too much fuel, leading to reduced engine power and engine shaking. Below are the reasons for insufficient engine air intake: 1. Clogged air filter: A blocked air filter increases intake resistance and reduces the amount of air entering the cylinders, resulting in incomplete fuel combustion and insufficient engine power. 2. Excessive carbon buildup in the throttle: Excessive carbon deposits on the throttle and surrounding intake passages alter the cross-sectional area of the air channels, preventing the control unit from precisely regulating the air intake. This also leads to insufficient air intake, causing the air-fuel mixture to be either too rich or too lean, resulting in engine shaking.
