OK Has any one ever done this, put a d16z6 intoa 93 sedan, cuz I need some info if this is any diferent then putting into a HB or coupe. I put one in a 94 HB and it worked perfectly fine from th efirst time I cranked it over. But this sedan has been a diffent story. I finally go the engine down from 5 codes to 2 the 2 thats left are Idle air control valve and Primary Oxygen sensor heater. can u give me any Ideas on how to get rid of these codes. The egine idles at 2 grand and bouces. Will fixing these codes fix the idle.
