Youve got the meter on the wrong setting, set it to ohms and test it that way. The resistance should change as the vacuum increases


I am putting my red lead on the green wire and black lead on the black wire. I am also putting my red lead on the brown wire and my black lead on the black wire. I have tried my meter set on different Ohm settings and I am not getting a reading. The car has new MAP and new injectors and still runs the same. I took it for a spin and it coughed up a code 33 again. It seems to be running rich, idling rough and runs even rougher at higher RPM's. I think its vacuum related. Once I had to almost push the brake pedal to the floor to get it to stop. First time its done that. I am not sure where to go from here.
