2 things. reroute your pcv too while your blocking and fingering your egr! i cant beleive the thick black crud that i now drain onto the ground instead of dumping it right into the turbo! a necessary mod i.m.o. second i just had the exact same code #7 injector voltage or whatever, turns out my edge harness had worn through and i had bare wires bouncing around. clear the injector code then completely unplug the edge harness and drive it. i bet it will run fine with no codes!
