Sounds like you've eliminated a lot of things. One other possibility- a
manifold vacuum leak. Those can be tough to find. Check the usual
suspects (hoses and their connections) and then there is the nasty one-
the lower manifold seals.
Explorers have had problems with bad lower intake manifold seals, so
much so that the factory paid to have them replaced. I haven't
experienced that myself, just read about it. Maybe someone who's
experienced this problem will describe the symptoms and any
troubleshooting tips they learned.
