I just got done doing the b16a swap, and I know I saw the answer to this question somewhere but I can’t remember where. My car won’t stay at the same rpm’s when it’s idleing, it will rev anywhere between 1000 rpms and 2000 rpms and it will keep going up and down. Can anyone help me out? could be something I forgot to hook up or something?
check your EACV…that controllers initial idle for warmup…check for codes as well…but most definitely hook up your O2 sensors…the ECU needs those to monitor oxygen content.
