I have 17,500 miles on my car go to start it the temp was -1F and it starts missing and the idle is everywhere. Call the dealer they say dont drive it and they have it towed in today they call me and turns out it is some kit that they need and dont have one in stock anywhere and he said there is a TSB on it anyone heard of this I asked what it was and he said he wasnt sure and that he was just the service writer
