tested the coil, all good, checked again for vac leaks with crab cleaner spray...could not find a vac leak??
removed idle air control valve, washed the gunk out of the valve port with carb cleaner, fitted new valve.
removed EGR valve, cleaned it up a little, re-fitted it with a new gasket.
re-routed all spark plug wires and fitted lots of new separators in an effort to reduce all arcing, looks way better and seems to have made a difference with the van idling on the driveway in park and Drive for a long period of time....road test tomorrow in the FL heat will be the real test!
