hello fella's im new around here . i own a 96 corolla with the 1.8 5 speed . i dont wanna make it fast or anything i just need some info on a vac switch (i think its called ) it looks like a pipe plug with 2 vac nipples on it for hot and cold im told . well i broke mine and was wondering if i can just block this off . i was told i could, but i dont know if this guy knows what he is talking about . one vac line goes to the throttle body and the other goes to the vapor canister .

thanks in advance
billy
