他说的那个味道可能就是 Transmission fluid 高温下变质发出的味道。开始只是跛行，随后整个儿变速箱就坏掉了。换变速箱二手的都超过整车价值了。换 Transmission fluid，dealer 要价超过300，交叉一下估计不会超过200$.交叉就是 HONDA 车找 TOYOTA or GMC or FORD,,,
冬天，极寒天气下，坚决不要开这种车上路。在加拿大，一定要开一部靠得住的车。别的还可以妥协，车不能。
What does this mean? Tech notes
The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persists more tests needs to be done to diagnose problem, see "Possible Causes"
师傅可能只是断了电池清除了P0172，但很可能会回来。
最开始P0172是fuel system too rich, 原因有很多，所以要一步步排查，而首先要查的是fuel pressure。压力太大会导致油气混合太浓，而压力太大有很多原因。
如果不是压力问题，有可能是vacuum leak，也有可能是thermostat坏了，这都有可能造成too rich。

已转告: About fuel pressure, first to check fuel pressure since overhead fuel pressure could cause dense fuel. If fuel pressure normal, check vacuum leak, or thermostat broken issue, which could cause too rich.
