I don't know how the manifolds are designed on a 2001 'lude but it's
conceivable that if the plug is in the intake manifold that it might work
it's way into a cylinder. The results would be disastrous. Can you see the
plug? If so, can you grab it with a spring type claw tool such as
http://tinyurl.com/ebwfy ? I realize that this might not be possible due to
the small access hole that you have available. If the plug is loose and
rolling around, then the safest approach would be to remove the manifold and
get the plug out. This would probably be the procedure I would follow if it
were my car.
