I have a lot of knocking noise from the engine compartment more often when coming to a stop and then idling after driving for a while.There isn't any knocking while driving. I've been told by the dealer that it is the direct fuel injectors. On a second inquiry I was told it was the dual fuel pumps. In both cases I was told it is normal. When I have people in my car they ask what that knocking noise is!!!!After driving my LS430 for 6 years with an absolutely silent engine I find this very annoying. Anyone have any suggestions?
