Ok. I am down to my last few problems. I need answers for this and my timing question. I Put a 97 b18b1 in my 94 civic dx. It runs. There is a blck can on the firewall. Says OVC on it..I know that the small hose goes to the sensor on the top of the Intake manifold. But there is a little bit bigger hose right next to it and I cant find the spot for it. Now when I removed my stock engine I labled everything. The label for the hose I put on was front throttle body..But there isnt a spot on this throttle body for it. And the lables where from last summer so I forgot where it came from.. What should I do with it or where does this go... I looked on the old DX engine there is a extra nipple on the throttle body where it went but the integra one doesnt have that nipple..
