What Causes the Jerking Sensation When Releasing the Accelerator in a Teana?

[IsabellaAnn]

Teana experiencing a jerking sensation when releasing the accelerator can be attributed to reasons such as engine oil passage blockage and jerking during automatic transmission vehicle starts. Specific explanations are as follows: Engine Oil Passage Blockage: The combustion of fuel, which is also the power source of the engine, is determined by the engine's ignition, intake, and fuel injectors. If the intake volume decreases, ignition weakens, or the amount of fuel injected reduces, the power output will be insufficient, leading to a jerking sensation. Jerking Sensation During Automatic Transmission Vehicle Starts: When attempting to accelerate quickly during driving, it requires pressing the accelerator deeply. At this point, the automatic transmission will automatically downshift to increase the engine speed. Once the speed reaches a certain level, it will upshift. After upshifting, because the speed will drop significantly, a relatively noticeable jerking sensation will occur. This situation is more common in automatic transmission models with fewer gears, such as 4-speed automatic models.
