08 finidi QX60 fault code Air leakage in intake pipe

Air leakage in the intake pipe of an automobile will cause insufficient air (oxygen) for combustion in the cylinder, insufficient combustion, poor mixing ratio, and no acceleration force, and will tremble in severe cases. It is recommended to repair it as soon as possible. When the engine does work, it must take in air. After the air passes through the throttle body, different pressures will be formed in the intake manifold according to the different intake volume. The larger the throttle opening (when stepping on the accelerator pedal deeply), the more the air intake, the smaller the negative pressure and the smaller the throttle opening (when stepping on the accelerator pedal lightly or not, the negative pressure will increase).
