I removed the intake to replace spark plugs and valve cover gaskets. The van was running OK before I started work. After reassembling when I start the van the RPM goes to about 4000 and than comes back down to about 3500 RPM. I have check for air leaks. I believe that I reinstalled all of the lines correctly but now am unsure. I check all of the connections I disconnected and all locks which I did hear. Suggestions?
You have a MASSIVE engine vacuum leak.

Replace the PVC valve, it's probably clogged.

there should be a box at the other end of the intake hose with two clamps on it after unclamping it pull the top away from the box then pull up

It is possible the tubes are leaking at the bottom but highly unlikely. There is next to 0 oil pressure in that area so the tubes would actually drain if leaking. I would start with the tube seals and gaskets as you have already planned and check it again later down the road like at the next oil change interval. You're on the right track for the repair, just be patient with the intake plenum and you'll do fine.

you need to remove the intake to replace the front plugs
it's equipted with coil packs so you don't have to replace wires and cap
most of the time you don't need to replace gasket but you can get one just in case.
make sure you put the plugs that the manufacture recomended
