Here's the deal. I'm trying to regester my "new" car (a '91 CRX with a B18A), but it failed the emissions test (the previous owner is one of those lucky bastards from FL). Now I'm trying to complete the gas recirculation and emissions systems. From a visual inspection, I can only spot a missing component as outlined on the picture. I can't find its purpose on my lousy Haynes Manual. Can somebody tell me what this valve(?) is for? To what it is connected to? Also, would you guys have a vacuum hose diagram for '92-'93 Integra LS? Thanks in advance for your help. PD: BTW, this is a picture of my engine bay: Can you guys spot other missing emissions related components? Thanks again!
