Ok. Heres what happened. All my friends were hyped that I was doing an engine swap and they all offered to help. My friends dad let me use his shop and his help would have been the greatest being that he is a decent mechanic. here is how they helped. One kid held up my hood while I unbolted it. Another took off my left wheel. And the experienced mechanic unplugged my old wiring harness and I didnt get to see where anything went. So I got stuck doing the entire swap all by myself. My car is a 92 dx hatch and my new engine is a d15b with a p08 ecu I got from hmotorsonline.com. I got the motor in and I got it started. When I hit the gas, it delays before it revs. after a while, it will just die. I dont have an o2 sensor hooked up yet so I am hoping this is the problem. Another thing, I have a small hose and nowhere to put it. It comes off a black tank lookin thing on the firewall. I think its a vacuum hose. I also have a two prong wire from my harness. It is loomed with the throttle position sensor clip and the wire colors are black/yellow, and blue/yellow. One morde thing, which wire do I connect my single wire o2 sensor to? my choices are black, black, white, or green.. Oh and shouldnt I get a check engine light? Im not. Sorry this is so long but Ive done way too much work for this to not work. Thank you all very much.
