Re: accord sedan 98 v6
once in awhile my 'check engine' light comes on and when i get it checked out i get 1298 which turns out to be: IDM Failure.
there's no other description and no one seems to know what that is. whatever it is, i'm guessing that it's something non-specific so it is hard to describe or pinpoint in words. but can someone still explain the gist of this and if it's something that needs attention asap or not?

thanks for any help~
