On my 5 when it is warming up in the morning I hear it bubble out the exhaust and you can feel it in the car to. It has done this since new so I know it's not the tune. Does anyone else get this to? I was thinking maybe the plugs are crap or not gapped right. Other cars that I have had never did this and my suv doesn't do it also so I am lost on this one. Also when it is warmed up I can rev it up past 3k and let off and I can hear the bubble when it starts to touch 2k and continues on down to idle but at idle I hear nothing.
Really strange!
