汽车抖动,主要是缸内汽油燃烧的问题导致的. 那么怠速抖动是不是也一样呢?
如果是,那么网上有人建议的:
检查火花塞
检查air filter
清理throttle body(不知道和throttle valve是不是一个东西?)
清理mass airflow sensor
清理fuel injector
可能mount破了
应该是可行的.
基本上就是把进气进油的部件都检查一下. 问题是这些东西我都不知道是什么...(除了
火花塞和air filter)
还有,idle时转速低于正常水平,不知道能从这里面看出什么问题. |

Achieving maximum acceleration or hill climbing, while avoiding engine
speeds higher than a certain limit (e.g. 3000 or 4000 RPM), is difficult
since it requires avoiding triggering the kick-down-switch. Avoiding
triggering the kick-down-switch requires a good feel of the throttle pedal,
but use of full throttle can still be achieved with a little sensitivity as
the kick-down button is only activated beyond the normal full opening of the
