can i use the d15b manifold and the throttle body from the d15b... and still keep it wired obd0... its not the wireing im having problems with its the vacuum lines... i also cant get the damn thing to idle at less than 1700 rpm and the idle adjustment screw is all the way in...

in the si manifold there is three vacuum ports on the manifold and on the throttle body there is a kind of diaphram... the d15b manifold has 1 manifold vacuum port and one ported vacuum port and no diaphram on the t/b

does the map sensor need to be hooked up to a manifold vacuum or a ported vacuum... anybody that has this setup that is running right i would greatly appreciate your help

i had the same problem nwith my d15b into 88 hf swap
just take out that vacuum assemble on the firewall that has the map
use the map sensor on the d15b tb then you should have one line form tb to evap canister
that should be all
