Ole Blue needs work
I've had this truck for a while,its bone stock all original,4350,stock intake,stock emissions stuff,but runs rough at idle...I think some vacuum lines aren't right,
But I've never found the correct vacuum diagram for it and the one on the truck is gone...
and the truck has always run rough,no matter whats been done including recent head work
Its a 1978 f150 ranger XLT Trailer Special,
federal 460.J code,
no EGR or any signs of one,
I've got 2 thermal 3port vacuum switches, 1 in the T-stat housing, and another in the intake, just in front of the carb,
And 1 electric solenoid mounted on pass. side valve cover,along with 2 or 3 vacuum dampeners,
Its not alot, needs to be correct before I move forward with other possible causes.
Anyone know of a place, or the best manual that will have this info?
Thanks,

I've seen all the diagrams on this forum, and some are 460,but most are for calif. 460, or 400's...
and have searched many places on the net for this particular setup with no luck.
Thanks
