vaccuum pressure
Hey all, I cannot for life of me find how much vaccuum i should have at the manifold ( or a range of vaccuum).
84, 22r california emissions,4x4, m/t.
trying to chase a series of rough idle problems. truck sat for several years with the hood up before i got my hands it. so alot componets were dry rotted and failing.

I found the spec in Toyota's 22R supplementary "Repair Manual For 1982 Emission Control". I don't have the 1984 spec but it should be the same.
It states that intake manifold vacuum, at idle, is "more than 400mmHg (15.75 in.Hg)".
