Those pics are giving me a headache...please resize them. Anyway, best bet for you is to take a vacuum gauge and start at the EGR valve, and work your way backwards until you find a hose that doesn't keep vacuum under any circumstances. The FSM outlines how to test each component of the EGR system, might want to take a look.

 

Check to see if your temp sensor connector is corroded. Mine detonated at WOT when the terminals were bad.

Check all your connectors, that they are all fully engaged.
Unfortunatly it could be an injector connector. For the rear bank of injectors, use the subharness to check that their resistance is okay.
