hi can anyone help me Ford says they have no diagrams there is no diagram under the hood and I am lost. I need the vacuum diagram for a 97 4.2 L. Just dropped in a new engine and it runs like crap so I assume it is all vacuum problems and I am not sure what I hooked up wrong.
Thanks
Byron

 

Go to a salvage yard and look at the radiator cover on a junker for the diagram.
