Have a rattely/buzzing noise underhood when "floating", neither accelerating nor accererating. I'm thinking it might be the EGR but don't really know. Wife refuses to drive car down highway with hood open and me under it to see for sure where the noise is emanating from. Most wives are afraid of this kind of thing, I think. Anyway, rather than turn to a different wife I ask for your sage comments. By the way, the car runs fine.
Thanks!
Thanks!
