Idle stability and sudden acceleration jitter of overbearing 4000

There are too many impurities in the accelerator dust. When the overbearing 4000 car is idling, it doesn't need too much throttle when it is slow, but it needs a lot of throttle when it is accelerating rapidly. When there is too much dust and impurities in the accelerator, the rapid acceleration will cause the overbearing 4000 car to shake. Overbearing 4000, a newly developed new generation suv, is equipped with a newly developed Toyota six-cylinder EFI 1gr-fev6 engine with a displacement of 3956cc, which has good power performance and high environmental protection.
