I have a 89 t-bird sc, I was driving down the highway and then poof i get a vacuum leak, i looked under the hood and the hose going to the PFE popped off. Where does this hose leed to?
Is that the code you got or what? I can't figure out how you know where it goes, but don't know where it is.
If it's only on the 89' cars then I think you are refering to the doohicky on the rear of the inlet plenum. Which I think goes to the lower intake manifold to lower IC tube adapter.
