The 4.6 and 5.4 are close in design. I also looked at the schematic for this truck, the PCM does not apply a ground to open the EGR, it rather applies voltage, from a signal of the DPFE to the EVR through the PCM to open the EGR.

WOW! Ok then. Well I was mistakenly under the impression that the pcm would send a ground because when I checked the vehicle at idle there was a constant + signal. Well now here is another issue. KOER the EVR is constantly hot. There is no ground then. I have not checked the EVR KOEO to see if the signal was still hot. Regardeless the EVR has no ground. I really need more time with this truck. The intake will come off and be cleaned. Now I need to figure out this electrical shizzle. I wish this truck had balls so that I could kick them bitches
