What to Do When the Car Makes a Zizi Sound When Pressing the Accelerator?

[NorahRose]

When the car makes a zizi sound when pressing the accelerator, here are the inspection methods: 1. It could be the sound of the fuel pump working. Sometimes, the fuel pump may produce a zizi noise when operating, and the sound becomes louder as the accelerator is pressed harder. 2. It might be a faulty clutch release bearing. Try pressing the accelerator; if the car runs normally but does not accelerate, this indicates obvious slipping, mostly due to worn clutch plates. If there is a zizi noise, the clutch bearing may be damaged. 3. Check if there is any air leakage in the engine's intake pipe. Increasing the air intake by pressing the accelerator can cause a zizi noise due to air leakage. Check if the air filter is properly installed and if there are any damages or looseness in the intake pipe. 4. Check if the engine belt is aged, loose, or slipping, and replace the belt tensioner if necessary.
