just for reference i have alreayd searched new post and archives and found nothing to help.

i just got done doing a D15b swap into a 92 Civic Dx (Prewired for vtec). everything starts and runs but i am throwing 3 codes. #3, #5, #14. both 3 and 5 are for Map sensor. and 14 is for Iac.

Swap is d15b, using a 92 Ex wiring harness. chipped p28 (auto to manual). all plugs are connected. only thing i can see thats weird is the 92 dx has the map sensor on the firewall and the motor i have has it on the intake mani. i've tried switching the plugs, having one unplugged and the other connected and vise versa. and nothing seems to make it go away. car idles high with one connedted a certain way and the other drops idle to normal.

any help on this would be great.

 

up for the afternoon guys.
