ported vacuum on MPFI
I may have lied to you, from this 1995 magnum vac hose routing diagram, there are two ports on the front of the TB. One labeled M and one labeled P.
M goes to the map sensor and P goes to the evap canister with a check valve in line. I’m guessing P is ported. You could hook a gauge up and try it if you have the port.
And I looked at my 2001 5.9 and sure enough right next to the map sensor I have a plugged port.
