Vacuum Leak? 2001 Excursion
I have searched both under the hood and here... no answers yet.
2001 6.8, California model. I have what sounds like a significant vacuum leak. I have felt all around by the Throttle body and ICV and cannot feel, see or find anything cracked or loose. I also sprayed a bunch of carb cleaner everywhere I suspected and cannot find it. It there a pronounced vacuum sound naturally?
I did check all the elbows I can find with no cracks and the PCV while loose in the grommet and barely sucking vacuum, messing with it does not appear to change the noise.
