2003 honda pilot exl
Hello everyone. First time poster. My gf pilot decided to throw p0505 last week. Ive cleaned the iacv made sure it was working. But the code and the idle surge remained. So i decided to do a vacuum leak test with a smoke machine. And i found that smoke was coming out of the hole beside lower front intake manifold or so i seen atleast. The hole is in the cyclinder head. I already check the bolt on the lower intake manifold and its all good. So my question is am i missing something here. Im out of ideas here.
