I just built a ls vtec and its idling at 2800 rpms. and i know its because the vaccum lines. Its a b18a1 block and b16 head. The block has a black breather block and the lines coming out of it are hooked up and idk where they go. Then i have one major vaccum lines coming out of the front of the intake manifold. I was wondering if i could just put a air filter on it? or could someone get a vaccum line diagram?
