Hey I put an Ls into my Crx a couple weeks ago, I'm running a obd0 pr4, all stock, unchipped, and all stock motor, besides an intake and full exhaust, my problem is the thing is running pig rich, I can smell the unburnt fuel after a hard pull, like its boosted or something, and you can see the black smoke from the fuel start puffing out at about 5500 rpms. Is this hurting my performance? I know it can't be good considering it isn't under boost, I should be picking up an AFC sometime soon, so I can lean it out with that right? thanks for any help guys. -Ben
