Re: Serious Issue
if the gasket doesnt seal it off i would guess that the Fiav portion of the lower half of the throttle body is damaged internally somehow.
also if your talking about rtv sealant your supposed to let it cure for 24 hours before use. so if you have done gasket sealer twice since this topic was posted i would guess thats why it didnt work.
either way the fiav portion of the throttle body is janky and old school plus prone to failure. after so many heat cycles the wax breaks down or the mechanism can fail inside.
i got the bypass plate myself and it solved a lot of my idle issues and boost leaks.
