New B4000 owner, about to lose it over Check Engine Light

i think they make a solution you can spray on the lines that will bubble at the leaks.

you can go to oreilly auto parts and rent a fuel pressure gauge. Open your hood and look at the fuel rail. At the end of the rail there is a black cap that looks like the one on your wheel. Remove that cap and get a rag and push the center of the valve in with something and use the rag to soak up the fuel that will squirt out. Now install the gauge on the valve. turn on your key and see if the pressure builds. Record that measurement somewhere. I dont remember what the spec is for it, but call a ford dealer and they could probably tell ya.

your running unleaded gas right?? E85 can cause the codes(just checking the obvious)

Grab a can of aerosol cab cleaner or brake cleaner and spray along the upper and lower intakes, if the idle drops while spraying along there you've got intake gaskets leaking.

The person that owned it before you may have bought an aftermarket PcV valve or IAC , I know those can throw codes like that. Make sure all your components are motorcraft. I was just talking to my mechanic about that yesterday. Good luck man.

I changed the PCV EGR and IAC today and it seems to have killed my vacuum leak, drove most of the afternoon and no error codes came back up, thank you guys so much.
