Have a 95 civic dx and a d15b jdm obd1 motor. So i have got the motor all the way in including fluids and all. Noticed a few issues. evaporative emission (evap) purge control solenoid does not have a place on the intake manifold to be screwed to and also does not have the barb to plug in the lower hose below the actual mount point on the manifold. do i need it? will i get codes thrown at me if it is not in? Motor does run without it. Where can i find the info for the 4 wire o2 conversion? I found it before but can remember where i found it. Also broke my map sensor plug. anyone know where i can pick one of those up? I have to go wire my vtec in right now so i can check that off the list. Bought a conversion harness off ebay to do it. 20 bucks or something. Please help.
