Loud humming noise from air intake.
I have replaced the PCV valve. Did not stop then I replaced the idol air control valve and it is still humming. I'm just wondering if my manifold could possibly be messed up as well. I am just a tube mechanic and have never messed with this side of things before. HELP- Gregroe75
