LS newbie question vacuum port plug i've got an '04 5.3L that i'm putting into my '89 suburban. the avalanche the engine came from was hydro-boost so the vacuum port on the back of the manifold is plugged. i need to get the plug out to install an adapter but don't know how to remove it. i pulled on it, it wiggles a little. i've been told it doesn't just pull out but i haven't found out how you remove it. all this plastic stuff scares me, i'm a heavy equipment mechanic, i'm afraid of breaking it.
the plug in question.
