So my car (1995 dx w/ d15b swap using stock harness and P28 ECU) is running good now minus 3 little bugs i can't seem to get rid of. My check engine light is on and it's throwing codes 10 (intake air temperature sensor) and 14 (idle air control valve). I went to a local garage and asked for the wireing diagram of a dx harness. So i got it and come to find out all my wires are correct. I tried to reset my ECU but for some reason it didn't do anything. Another minor thing is that when at 1,500rpm the motor revs a little by itself from 1,500-1,600 and when at low rpm when i let off the gas the car jumps around a lot. IF anybody has any info on this it would be greatly appreciated. Thought this swap was supposed to be easy, even for a NEWBIE . But then again I guess you always run into problems

use your sensors off of your old motor( same things) ....also my codes wont reset for some reason until I pulled my negative cable

I'd say your sensors are bad also...

Its seems to me I had the same problem at one point. I think the iat and iac connectors are the same and the wire colors match. Try switching the connectors, I could be wrong though. Let me know.

i have tried everyting that everyone has said here...i even took my IACV off my old motor which i knew worked and it is still fucked up. I'm almost at the point where i'm gogn to bring it to a dealer

Have you tried using the old ECU to see if it comes up with the same codes. you could have an ECU problem. ALso make sure the thermostat ground wires are tight. Loosen them and tighten them back to be sure.
