1994 4runner 3.0L 3VZE engine code 71 throttle port E no vacuum at 3500 RPM

Hi,
I am inquiring on an issue I ran into on 3vze 1994 toyota 4runner 3.0l engine. The vehicles check engine light is on. I ran test and pulled code 71. This refers to EGR system malfunction. I did multiple checks, suck air on the EGR and verified engine bogging and wants to die, checked vacuum at the q port of egr modulator. no vacuum. I then checked vacuum from the 3 ports at the throttle body. P E R. R had vacuum on my gauge when reving engine up, P had vacuum when reving engine up also, but port E from the throttle body to port P on the egr modulator had no vaccum? I verified at the throttle body port again to make sure and still no vacuum out throttle body metal line? my thoughts is to replace the throttle body??? anyone got any feedback on this? vehicle symptoms are idle drops and gets rough when braking or when throttle is slightly pushed???

 

Did you ever get this figured out? Going through the exact same thing now with my 93 3.0.
Thanks
