vacuum schematics for 1993 dakota V6 3.9L

Asked by Nov 27, 2010 at 09:33 PM about the 1993 Dodge Dakota

Question type: Maintenance & Repair

My son is stuck in a small town in Georgia and his truck is stuck at a very high idle, so high that the engine is overheating when they start it and he is concerned he is going to blow the engine.  He and his friends suspect a vacuum problem and need to get a vacuum schematic so they can figure out what is going on.  He only has internet on his phone so I'm trying to get some info for him.  He put a new idle sensor on it but it didn't help.  Is there a place to get the schematic online?  Any other ideas about what is causing this?  He needs to get back to Jacksonville, Florida for work Tuesday, but he has limited money, internet and parts stores in the little town he is in.  Any help would be MOST appreciated!!
