What are the symptoms of insufficient engine air intake?

The symptom of insufficient engine air intake is more fuel and less air, resulting in insufficient engine power, engine shaking, etc. The following are the reasons for insufficient engine air intake: 1. Air filter clogging: The clogging of the air filter increases the intake resistance and reduces the amount of air entering the cylinder, leading to incomplete fuel combustion and insufficient engine power. 2. Excessive carbon deposits on the throttle: Excessive carbon deposits on the throttle and surrounding intake passages change the cross-sectional area of the air passage, making it impossible for the control unit to precisely control the air intake, which also leads to insufficient air intake, excessively rich or lean mixture, and engine shaking.
Last time I was driving, I noticed the engine was having insufficient air intake, which was really annoying. The most obvious symptoms were reduced power output - stepping on the gas pedal felt like stepping on a sponge, and the acceleration was painfully slow. Fuel consumption also skyrocketed - what used to last a week now only lasts three days, which is hard on the wallet. At idle, the car shakes noticeably, feeling like it might stall at any moment, requiring me to keep my foot on the brake at red lights. Starting the engine is also difficult, taking several turns before it fires up. The engine sound is abnormal too, making a wheezing noise like it's gasping for breath. These issues might be caused by a dirty air filter blocking the intake or leaks in the intake piping. If not repaired promptly, engine wear will increase, leading to even higher fuel consumption in the long run.
As someone who frequently tinkers with cars, I can clearly recognize the signs of insufficient air intake: the engine feels generally weak and sluggish, with a delayed throttle response when accelerating, accompanied by a significant increase in fuel consumption; unstable idling, noticeable vibrations, or frequent stalling; abnormal difficulty in starting; sometimes strange whistling or buzzing sounds can be heard from the intake system; it may also lead to emission issues like blackened exhaust. These problems are often caused by a dirty air filter, a cracked intake pipe, or faulty sensors. It's essential to check the cleanliness of the filter and the sealing of the pipes. Regular maintenance can prevent these minor issues from accumulating into major troubles.
After driving various cars, I have a deep understanding of the symptoms of insufficient air intake: a noticeable drop in power, difficulty accelerating or even shaking when climbing hills; the car is prone to shaking or stalling during idle; a significant unexplained increase in fuel consumption; difficulty starting, often requiring multiple attempts; and the engine sound also seems muffled. If ignored for a long time, it can affect engine performance and increase maintenance costs. It's important to promptly check whether the air filter or pipes are clogged or leaking.
