The PDX bound Dmax has made it home. The dealer read the codes and came up with code 93 and code 87. What say ye experts?

A little more google work and It looks like these are the codes that go hand in hand with "replace all 8 injectors." I would have thought that this problem was more constant, but I'm just a Diesel neophyte.
