The van has the newer plastic type DPFE. It might come down to having a mechanic look at it. But if I can do a little dirty work myself, I'm hoping I might be able to find the problem out.
MAF was cleaned 2 weeks ago when I cleaned the IAC motor, air filter is a K&N that was cleaned not too long ago. As for the fuel filter, I don't know the last time it was changed. If it was the problem per say for the rough idle and stumble when coming to a stop. Would it not also cause a fuel starving issue on acceleration and cruising speed? Which the van is not experiencing.
I'm also thinking of running a can of Seafoam in it, to see if it's a carbon build up that's causing it?
Meanmchn, thanks for the link!!
Found the problem!! I started checking over the vacuum lines, pulled one of the elbows off (sorry no pic) and it was killed, exterior of the elbow looked fine but the rest that wasn't seen that attached to the manifold was destroyed causing a vacuum leak. Off to the Ford store, showed him the rubber elbow, said part doesn't exist. Looks through his parts bin finds a similar item from a Focus that has the elbow and a piece of metal tubing 8" long. Says this piece is $32, want it? I said no, thanked him for his time. Off to Crappy Tire, no part... Part Source, no part. Head back home, found a small diameter heater hose that I had, clamped it in place. Fired up the van, no more rough idle or stumble. Now I need to find this elbow, somewhere..

Looks like a 90 deg. Plug wire bolt would work perfect for that.
Glad you found the problem, good job.
It's where I suspected you had an issue.
As said above or just use a longer section of straight hose.
Pretty sure I've see the 90deg hose in the help parts at CTC or a jobber.
I thought the same, a 90 deg plug boot would work perfect, but I don't have one handy.
I used a curved heater hose which really works quite well. Looking at other Windstars online they have a similar setup of what I did.
I hit up the help section at CT and PS, was surprised not to find a simple 90' elbow hose.
Thanks gents for all the help and suggestions!!
had the same issue with my 98 f 150 3.8....
