i need help figuring out what vacuum hose is supposed to connect to the barb on the intake silencer. i can't seem to find a hose to connect to it. it's been 4 days since i tore it apart and my memory is a little fuzzy. this all started 4 days ago when i got a po122 code(i think). i pulled the throttle body and IAC, installed a new throttle position sensor, but had to wait a few days on a new IAC gasket. i've got it back together and its running, but now it idles around 2k rpms. i'm aware the problem could be the IAC valve itself but i want to eliminate the vacuum problem before i tear it apart again. i tried looking at pics but can't seem to find one with the right angle to show me where it goes. any help would be appreciated.
