I know this isn't a common swap but i just wanted to get my 93 civic dx running so i bought a VX engine. The swap was easy but however the ecu code 41 comes on and I'm sure that its because the vx motor has a 7 wire O2 and i used my original 4 wire harness. Iv searched a coupe of forms now and i cant find anything on this swap(probably because no one wants less horsepower) This was my first swap and if i can get this working ill be looking into getting a B16a2 swap. The car was in bad condition when i got it and i wanted to get it running first. If someone can help my i would be very grateful.
