I just installed a MAC cold air induction on a 94 gt and there is a stem that has nothing over it. It is located on the rightside tubing of the cold air induction. It's the first stem on it coming from the throttle body and it is pointing toward the alternator. Does any tubing go over it, do i plug it or is it suppose to be open? I tried to attach some pics but it didnt work. If you cannot understand my descripition tell me and i can try to post some pics again.
