I have a 2000 explorer Limited, 5.0 L 8 Cyl, engine code P. I been getting radon misses and found my wires were shot. When replacing the wires, I discovered that a vacuum line appears to have melted- problem is I can only locate one half of the equation. I'm sure I'm just over looking it. can any on tell me where this vacuum line is supposed to be heading so I can find the other end?? It is while, exiting a double port on the driver side, just in front of and below the intake manifold. One vacuum line runs across to the passenger side and into the area of the air intake. The other is the one that is burned off. See pics. Thank you!
