your lucky day

check your plugs to see if they r tight.   In my case, one of them (#2) is so loose that i was able to remove it by hand (with plug socket).   I replaced all my 6 plugs without removing anything.  give it a try? at least re-tighten the front plugs is easy.

• 不大可能是这个原因，1 个月前换的新轮胎，才跑不到1000迈。不过我明天还是查一下。 -ddy- ♂ (0 bytes) () 02/22/2016 postreply 19:35:35

• 哦，这个有可能，spark plug 还是原装的（现在准确里程是8.5万迈， 不是10万）。等天气暖和后，学着DIY换掉， -ddy- ♂ (38 bytes) () 02/23/2016 postreply 19:09:40
