What are the symptoms of an engine intake pipe leak?

The symptoms of an engine intake pipe leak are: 1. Insufficient engine power, difficulty starting; 2. Increased nitrogen oxide emissions in the exhaust; 3. Higher engine idle speed; 4. Noise from the engine intake pipe; 5. Increased fuel consumption. The function of the engine intake manifold is to maintain driving safety, located between the throttle valve and the engine intake valve, and it is the intake pipeline from the carburetor or throttle body to the intake port of the cylinder head. The requirements for the plastic material of the engine intake manifold are: 1. High temperature resistance; 2. High strength; 3. Dimensional stability; 4. Chemical stability; 5. Thermal aging stability.
Experienced drivers can clearly feel it after driving for a while. The car shakes violently at idle, and the tachometer dances up and down. When accelerating, there's no response when pressing the gas pedal, and climbing slopes feels weak and laborious. I've encountered this several times, and there's often a hissing sound under the hood, like a tire slowly leaking air. Fuel consumption spikes, and a full tank runs dozens of kilometers less than usual, which hurts the wallet. The check engine light also comes on, scaring you into stopping immediately and not daring to drive further. Upon inspection, it turns out the intake pipe seal is faulty, sucking in extra air and disrupting the air-fuel mixture. If not repaired promptly, engine wear increases, and there's even a risk of stalling. Pay more attention to sounds and vibrations while driving to detect issues early.
