Strange rumbling in certain light loads. 2006 5.7 hemi, has MDS. Noise in video can be heard around the 9-10 second mark, listen carefully for a change in engine noise. For more info for a diagnosis I must add is the noise goes away if I put the truck into tow/haul mode, by go away I mean it’s instant, almost to me seems like an mds issue since mds is shut off in tow haul, right? Any help is appreciated
