Wifes Jeep won't idle

Good morning !!
My wife's 96 grand Cherokee 4.0 in line six will not idle on its own.
She called me from work this morning and told me about it.
I am not a tec and I now this is an A bodies only site but if some one can help me with this I sure would appreciate it.
First I will disconnect the battery and then see if it will clear it self.
I will look for bad vacuum hoses and if a fuse went out.
I will see if I can find a book on it and check map censers, throttle position,
I don't think a fuel pump will go out like this or if a filter will make it not idle.
I am heading to her work know and let her drive the Dakota home.
Wish me luck making it home.
Thank's. Mike.
