#166005 theres no difference between the two .....

the only 6 vaccums are as follows.from memory....

1-from the vaccum canister to the top of the throttle body or depending on where the map sensor is to there(other location is on the firewall)

2-brake master cyl to intake

3-theres a small line from the vaccum canister that goes to the fire wall....

4-intake to fuel pressure regulator

5-valve cover to intake

6-theres another small line from the cvaccum canister to the vaccum sensor on the back of the intake manifold

yes it should fix it you defiantely had a vaccum leak ummm hows your tb gasket since thats the other thing id look for if that iacv didnt have it....

and also yea teh bottom hole is for coolant flow on the tb....

and i see you changed stuff around lol your first question was the difference between z6 and b7 vaccum lines..... makes my first post look well misplaced
