Im swapping intake manifolds and going with a metal screw, while my intakes off how can i take apart this box and clean it up or replace parts so it works flawlessly? Remove the IACV, try to preserve the gasket (unless you plan to get another one), clean the shit out of it with throttle body cleaner or whatever to get as much gunk out. Pretty straight forward; I did mine this summer. Clean the shit out of your intake manifold while you’re at it. ---
