      Hello!..i have an 04 explore with 89K. 4.0 liter, it sounds like I have a vacuum leak coming from the upper intake (very rough idle)..I just spent the last 2 days removing the upper intake and changed out all 6 blue gaskets with no change..it sounds like the puffing sound is coming from the intake itself from somewhere underneath it. I checked the vacume hoses and all appears ok. I even changed the plugs and wires with no change..any help or ideas would be appreciated!
