Jdm D15b Swap Gone Wrong?

[420SI]

I Just Installed A Jdm D15b Motor Into My 92 DX Hatch. The Car Doesnt Run Idle Right And Cuts Off After About 5 Min. Im Using A P28 Ecu. I Noticed The Intake Manifold Is Differnet From My D15b7, It Has A Electrical Vacuum Connector That Is Not On The D15b? The check engine light comes on. i took it to the local honda dealer and they tested the ecu and found that the mass air flow sensor and some igniter codes werent being read? i changed the igniter but same problem. if anyone has done this swap please help me out here! Does Anyone Know Why This Is Happening Please Help Me!!

try swapping your old d15b7 intake manifold unto the jdm motor.
