90 lx 5.0. What should stock fuel pressure with vacuum line off be? Car runs rich and I checked the pressure with the vacuum line off and it was 42#'s. Seems high to me but figured I would ask. The only thing done to the car is underdrive pulleys. With the line on it was 34#'s.
thats about right, i like to see 35on and 45 off..

OK Ill have to check some other things then.
Look to see if the O2 sensors are working properly. Does it have the correct injectors? I knew a guy that put in 30lb injectors in his 91LX without changing anything, ran very rich.
