91 civic running rich
 

i have a 91 civic hatchback with a d15b6 put in running off a dual point fuel injector. does this engine need a multipoint fuel injection to run properly. if so what needs to be swapped

swap it
 

i tried the whole switching from dual point to multi injection,if you want that done i'd suggest having it done by a pro.it's alota wire splicing and re routing your ecu.it'd be a lot easier just to get a Si motor and tranny and ecu along with the little box that you would see in the corner of the engine bay that makes the multi injection work.
