求教大牛关于Long Fuel Trim Data的问题
最近check engine亮了,我读了一下fuel trim data 如下
Short Term Fuel Trim Bank 1 5.47% Lean(-)
Short Term Fuel Trim Bank 2 7.81% Lean(-)
Long Term Fuel Trim Bank 1 0.00%
Long Term Fuel Trim Bank 2 5.47% Rich(+)
感觉Long term fuel trim bank 1的值有些奇怪,而且后面么有 lean, rich之类的东
西。
还请大牛不吝赐教,指点一下是什么问题。
多谢
