In Reply to: Plenum question... posted by PJ on December 20, 2000 at 14:39:20:


there is a tube that comes off the front lower section of the air plenum and on mine the actual metal has cracked and you can slide it on and off easily. Has this happened to anybody else? Can I have somebody weld this? Also does anybody know what kind off problems this would cause when running?

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.

HTH,
Ron-Man
