Vacuum leak tests in 300CE- for ILUVMILS
I have a miss and had replaced the ignition wires.
I also replaced the EGR valve with a new gasket but I did
not replace the fitting on the pipe that connects to the EGR, just
used the existing one.
I found the switch over valve had a leak, so I replaced that also.
I tried to pull vacuum on one of the ports on the intake manifold and it does not hold vacuum. Maybe I am doing something wrong! Or does this mean I have a leak??
Am using a Mity Vac
