Wire not connected to nothing ???
My daughter has a 2001 Ford Escape and there is a white wire that is not connected to anything, it is just wrapped around the coolant overflow hose. There is a black wire also, but that one is going to into the back of the engine somewhere. they are associated with the Engine coolant switch and the Idle air control valve and some other sensor by the MAF. I believe this is causing her cold engine stalling problem. I have a wireing diagram but don't no much about it. I think it should be hooked up to the PCM. Help
