Ok i bought a 92 Civic DX sedan with an Ls-vtec swap(OBD1 swap) a few months back. The car ran perfect, Idled at a consistant 800rpms, and didnt throw any codes. A couple weeks ago I picked up a 98 Civic Ex Coupe shell(OBD2A car) to put the Ls-v swap in.....Well long story short, we swapped the motor into the EK and im having some idling issues and im throwing a couple codes. The first code is Code 1 for an O2 sensor. The car has a chipped P72 that was tuned on Chrome at Revline in KC and when the tune was done they deleted O2 sensors so this code kind of confuses me. When the swap was in the 4 door i was getting 29mpgs and now its getting 23.2mpgs. The second code is Code 14 for the IACV. I knew it would throw that code and I thought i knew how to fix it.
I was told to use this to repin a plug on the dash harness:
Well when i was ready to repin that plug I looked at the Plug on my dash harness and saw this:
The black/blue wire is already moved and there is no orange wire. The car has never been swapped before to my knowledge and still had a D16y8 in it.
The car has a very inconsistant idle. Sometimes it will idle solid at 1k rpms, sometimes at about 1800rpms, but most of the time it will constantly bounce between 1k and 2200rpms.
We used the factory EX harness out of the EK and I bought an Obd2a to Obd1 Jumper harness from Ryan A to use. I think I have all the necessary info to get to the bottom of this posted but if anyone needs anymore info just let me know. Im hoping this is an easy fix.
