OK, thanks for the input guys.

Is this correct,DPFE= Differential Pressure Feedback EGR

I am having a hard time figuring out where everything is located on the engine. Is the following correct?

The EGR is back right and looks like a 3in sauser

DPFE is under the EGR

IAC valve is behind the EGR and looks just a little bigger than a roll of film, laying horizontaily.

Not sure what or where the pcv valve is?

O2 sensors
Bank 1, sen one is located here(first upstream sensor?)
Where is the other upstream sensor?
(basically where are the two upstream sensors?)

Thanks Andy

Does anyone have a picture of this stuff
