Likely to be sensor plugs where lambda sensors go in (as Demon says)........look at (left or right, can't remember which) exhaust under engine........happened to me and caused same confusion. The plugs are made of different material to exhaust (!) and therefore when they get hold and cold over several hundred cycles they work loose.
