Power Valve for a 1989 Grand Wagoneer.
Ok I just bought a 1989 grand wagoneer , Ran it through emissions and No Go. My carbons were at 216 , and the Nox was at .45 and the Hc was at 6.08. I have read the the power valve can stick and make your carbon really high. So I grabbed My hanes book , and guess what it is not in there . Where is this thing located at . The engine is the v-8 360. I am sooo lost. Also I have no pressure at all on the evap test. Got a big ZERO on that with a note that says no tank line???? Any help would be great ...
