    Vaccuum diagrams

    Im hunting a stutter in the tudor's idle, so I figured it was time to take an account of the vaccum hoses, EGR, IAC, etc. Other than the underhood diagram, do any of you have a link or PDF or something with a decent vaccuum chart for an 87 GM?

    I have the Chilton's for 89+ Panthers, I just dont know if there's anything different between that and my 87's setup, that I should be looking for.


    Thanks again mangs

    Ive got a CFI diagram I made up... and I have a 91 EVTM I could snap pics out of, but the 90-91 vacuum plumbing is way different than those for 86-89... Id try to find an EVTM for that year

      89 should be pretty much the same. The EVTM is the master guide, but it has nothing of the emissions controls. Thats in a separate book. The vacuum distribution under the hood is painfully simple if its pictured without any emissions stuff. Its actually not even complex with the emissions stuff there. The only part thats a bit scary looking is the climate control plumbing inside.
