There are two vacuum line fittings one is offset towards the front of the tb then one dirrectly on top. the one on top? I was told it goes to the charcoal canister? Can it be plugged?
I tried to take it out with an ez out, it broke inside, thought about drilling but metal shavings don't sound good in the intake, replace the throttlebody? It came broke when I bought it, call them? If it is an ez fix I don't want to go through that B.S.
