What Causes Engine Idle Vibration and Weak Acceleration?

[VioletAnn]

Introduction to the causes of engine idle vibration and weak acceleration: Car idle vibration and weak acceleration are generally caused by excessive carbon buildup in the throttle body, leading to poor air intake. As carbon deposits increase, fuel passages become clogged, engine performance declines, fuel consumption rises, and a series of complications may follow. Avoiding prolonged idling, driving more on highways, and regular oil changes are all measures to inhibit carbon buildup. There are mainly two ways to remove carbon deposits: 1. Manual cleaning of internal carbon deposits. 2. Using fuel additives to improve combustion and clean carbon deposits. Comparatively, manual cleaning requires disassembling the engine, which is a complex process, costly, and potentially harmful to the engine. In contrast, fuel additives are simple, convenient, relatively cheaper, and provide thorough cleaning.
