Well no more input on check engine light, so who can help on where I can find a diagram for all the vaccum lines I need to replace. I still got problems.
Just a couple of thoughts on this for you. Naturally, you looked under the hood for the decal that is supposed to be attached to the underside of the hood, drivers side, towards the windshield? At least thats where it is on my truck. I'm pretty sure that Chilton's manuals have the vacum diagrams for most domestic trucks and cars. I have also had good luck at the local library as they carry an extensive collection of Auto repair books. I know that my local Ford dealer will let me peruse their shop manuals for my specific truck any time I need to reference something like wiring harnesses or vacum lines and they have always been good about potocopying stuff for me.
If you know somebody who has a truck from the same year and engine family you could use that as a template to copy from, assuming that their vacum lines are all factory original and haven't been altered by anyone.
I don't know what else to suggest for you though - good luck in tracking down and fixing your vacum lines - I know that they can be a real PITA.
