Ok i just swapped in a z6 motor in my 94 cx and i've had nothing but problems. the car starts now but when i rev it, it sounds like a subaru and drives lame. I am using my old cx harness. I ran the extra 3 wires for the o2 sensor and there are no check engine lights.

it also idles low and then shuts off if i dont rev it. i dont know if its supposed to do this but when i plug out the iacv the car shuts off immediately. is there any repinning i have to do at the ecu?
