I got a 2000 ITR and recently put on a skunk2 IM but the bung on the back of the manifold for the evap. control valve wasn't there. But behind the #1 runner there was a small bung that on the ITR don't go to anything. So what I am asking is on a B16 that little bung on the back of the IM behind the #1 runner, where does that go to? I capped off that little bung and also capped of the evap. control valve vacume hose. It ran fine for a week then last night it threw a CEL. I am thinking of getting the evap.control valve hose to connect to that little bung. Any suggestions?
