xfv8, a lot of what is posted here will work for the P0174 code too. You are just looking at bank 2 vice bank 1. But, they are both common before the intake splits it left and right. So, ou would be looking at the lower IMT valve as your most likely source of the problem, but anything listed above may be it too.
