I have a 98 civic coupe ex. It idols good at a dead stop whether its in gear or not but wen u take off or give it a lil gas it idols up and down only between 1200-1900 rpm but if I give it a lil more gas its good. We checked idol control valve and its good my mechanic says it appears that the motor was swapped also cars harness seems to be an automatic because there's about 3 lil harnesses that hang by the tyranny. My mechanic thinks it's an electrical problem wire harness or computer. Its a d16y8 idk if maybe its the wrong Ecuador.help!!!!!!

 

I meant tranny and ecu dam phone
