I have an OBX intake manifold for my '92 civic dx...on the back of the stock manifold there is an EAC Valve (vaccum sensor) but on the OBX there is no place to put it! and...the fuel rail doesnt line up with the predrilled holes...
did someone sell me a bunk manifold or is there a mod?

shoot, OBX = junk, I'll tell you that straight up. Sounds as to me like you bought a POS intake manifold. I didn't even know OBX made intake manifolds. That is one part I would have never considered buying from OBX. Send it back and save more money up and get a Skunk2 manifold.
