I had the same issue for months on my 2001 savana it ended up being a vacuum leak and the way I found it was by waiting for the engine to cool remove the air filter and cap the hole where it inserts into the airbox then remove the console in the van pull the PCV valve out plug the hole on the valve cover disconnect the PCV valve from the hose and spray extra soapy water all around the engine then blow into the hose and look for bubbles. My leak was at the throttle body where the intake connects. HOPE THIS HELPS
