hello all!! First off 1978 straight 6 4.9L automatic F150 here, but having a rough time idling. Now i'm pretty sure all the vacuum lines are wrong because it idles like crap.

I do have the manual but there's specifically no 1978 vacuum diagram, nor do any of the ones in the book look like what i have. I'm trying to decipher it but all these acronyms are kinda hard to find out, but i'm getting it piece by piece.

so if anyone has alot of experience with these i'd love to know where all the vacuum lines go, timing advance, temp controlled vacuum switch, charcoal box lines, pcv (pressure control valve?) and egr and intake flap

well here's hoping! thanks all in advance!
