Vacuum Line Connection to Intake Manifold on 5.4L
I would like to diagnose my engines condition using a vacuum gauge. The manual says to go directly to the intake manifold to connect the gauge. On my 2001 Expedition 5.4L engine, I can not see any direct port on the intake manifold (upper or lower). Is there someone out there that can direct me to the proper location.....perhaps a photo would be most helpful. The picture in the Haynes manual was of no help.
