Why is my van not wanting to accelerate, skipping, dragging, & sounds like crap?

What is your question?

I step on gas but it hesitates to move almost like it wants to stale out, it movies slowly up to speed, it shakes/ skips, & it's got a metal on metal grinding/ winding sound from the pulleys.

What makes this problem better or worse?

It's don't seem to change

How long has your 2001 Ford Windstar had this problem?
