hi does anybody by any chance know what the small hose that comes out the left side of the air intake that goes over the engine on a 2.5 dse does and should it have a grommet because when I took it off to remove the inlet manifold I found a grommet that is kind of oval in shape but did not see it come out and can't get it back in the hole in the air intake I think it's supposed to be in for love nor money any help please
