throttle body and emissions vacuum lines?

[daemon240sx]

alright ived removed all the emissions stuff over there by the carbon canister and plugged up the vacuum lines under the throttle body, i was wondering what the vacuum port on the throttle body itself is for? i have heard its for the egr and ccs valve. is it ok if i just leave it with a vacuum plug on it? my car is acting weird. it pulls good tell about 3200rpm then takes forever to rev to 6500rpm or so (under load - free spin revs fine)any suggestions would be appreciated. (sorry if there is already another post like this, ive been searching google for hours)

maybe a good description of all the lines around the throttle body with a pic!

(heh forgot to mention i have a 93 240sx fastback. ka24de for now.)

instead of searching google, use the blinking red button up top.

Yep, cap those lines after you've pulled all the emissions equipment.
