where do the 3 vacuum lines on the back of the intake manifold go to? i know the one on the middle nipple goes to that little canister by the header kind of. but i dont know where the one on the driverside goes too. or the one on the passenger side either. and also that line thats supposed to go on the throttle body. i have that one going all the way around the back of the intake manifold and going to the little metal line thats connected to the chassis. i think its like a metal evap line. pictures would help if you could show me where they go. thanks

Passenger-side one goes to the EVAP canister. Middle is either capped off or goes to the cruise control, and the driver-side one goes to the EGR valve.

^^ That's a good link, but that doesn't help him as he has a 420a, not 4G63.

okay thanks but i have another question. where does the little gray hose thats connected to the chassis go. its down by where the alternator is but i had that plugged into the passenger side nipple so its pretty long. and i have a little problem. when the car idles for a little while and i go to drive it the evap or something goes to hell. then the rpms wont go up past like 3,000 or so. i had that same problem when i put my b16 in my civic and it turned out to be an idle air control valve. but when i unplug the hose that goes on top of the throttle body it fixes it. i have that hose going around the valve cover to the metal tube over buy the cam gears on the chassis. is that where its supposed to go??? thanks for the info.
