#133486 ok i know this is sort of posted in the wrong place

i have a 89 civic dx dpfi to mpfi
i recently decided to switch to a d15b7 intake manifold and on my old mani i blocked off all the sensors, however i did it on this one and i got a very fast bouncy idle do i have to put the eavc on?(does it have to have it to idle)

oh ya i found that if i put a screw in the bottom hole on the inside it will idle if you limit the air just right however it runs like shit unless im at w.o.t.

any help would help a lot
