This might seem a little strange, but it worked for me.  Two years ago, I
was having the same type of problems.  It was during a period of hard rains
that lasted for several days.  Finally, one day, I couldn't even get it to
start and run.  One of the guys in the math dept hauled out a can of WD-40
and we sprayed down all the electrical parts in the engine compartment,
including the wires, and the _inside_ of the distributor cap, let it sit for
5 minutes, and it fired right up and ran fairly smoothly! Give it a try next
time the van decides to get balky.  Good Luck.
