Vaccum Lines ????

:help: When i bought my 89 accord all of the vaccum lines were screwed up .. there is a couple missing . at the end of the intake there is two lines just vented to atmosphere. So i went on to all data(repair tech program) and brought up the vaccum line routing, but it doesnt show it for the a20a4....only the a3??? the only reason i think this is because there are components on the diagram that i dont even have.........

maybe cause the a4 is emmisons-less>>?? i would probably just plug them if i were you :dunno:

so what has to me vaccum fed for operation....
I know the distributor, fuel regulator ,but what else
