YEa it idles. I got it to idle at like 1000, cause it was rough., I have drivin it all around town and stuff, I mean don't get me wrong, it is still running pretty quick, but it is DEF not up to par, because I heard how my friends 91 Ls was running and they are pretty much same motor so idk. Think an ACTUAL LS wiring harness will do the trick!? I mean the D16Y7 ran fine on the wiring harness before, so idk there was jsut 1 sensor i didnt hook up it had soem vaccuum line attatched to it. idk what it is. Come on all 92-95 civic's tho.
