Yup, will lean your motor out at high RPM's
and will be almost certain demise...
You can use "JB Weld" to reattach it. I've done
many with the stuff.
While you're at it, check the two 90 degree elbow's on the throttlebodies too. The break loose
but aren't as apparent. They most likely won't fall out like the one on the plenum, but they will
loosen to the point where they will rotate. Check them. If they're loose, you can use JB Weld on them too. One of the elbow's on the TB's is the vacuum port for the power brake booster. The other is buried below the fuel rail near the center of the throttlebodies, around the idle air mixture screw. It's where the idle control valve picks up vacuum. Just be sure both surfaces are very clean before using JB Weld. Some brake clean on a rag or "Q-Tip" should do the trick.
