What's wrong with Buick Hideo's throttle?

Carbon deposition on the throttle of Pacific Auto Network leads to sticking problems, and the throttle needs to be cleaned. The supporting pin of accelerator pedal is worn, and butter lubrication can solve the problem. If it doesn't work, it can only be replaced. Electronic accelerator, check accelerator pedal mechanism and accelerator pedal sensor.

It is normal for a cold car to step on the accelerator to about 40 yards soon after it starts, and there will be a "click", which is the sound of ABS system starting. If there is a clicking sound when stepping on the accelerator, it is an abnormal phenomenon. At present, there is no good solution, so we all go to the 4S shop to replace the accelerator pedal.

The engine needs to inhale a lot of air when it is working. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, thus accelerating the wear of the piston group and the cylinder. Larger particles enter between the piston and the cylinder, which will cause serious "cylinder pulling" phenomenon. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand in the air and ensure sufficient and clean air to enter the cylinder.

In addition, try to pull out the fuel gauge and check whether there is abnormal sound when stepping on the accelerator. If there is no abnormal noise, it may be a clutch problem. When the turbocharger is working, the compressed air flow generated by the engine will be louder when the engine is pulling speed or stepping on the accelerator deeply. Step on the gas pedal lightly, but don't step on it to the end. Heavy stepping will produce this abnormal sound.
