Does any one have a chart showing all the vac lines on a gsr? My car is idling at about 1500-2000 steadly depending on how long ive bene driving and im sure its a vac leak but i cant find the hose. Ive checked all the ones that i could find for damage and they checked out all fine. One question ive been wondering is what does the little tube on the top of the TB goto? Ive tried routing it into the vac system but it doesnt seem to do anything
