Stupid High IDLE after changing spark plugs, high enough truck accelerates on its own
The hose I broke was the plastic one which comes out of the crankcase portal approx. 4-5 inches behind the plug nearest to the firewall on passenger side and is connected up to the PCV in the side of the oil filler neck. Today I just replaced the plastic hose with some thick walled rubber hose purchased from parts store. Solved the problem rather cheaply. Went ahead and put in a new PCV. Hopefully with the new rubber hose, I won't break anything the next time I change the plugs.

So I fixed the Issue, I found the Service Bulletin pdf for the PCV and crankcase vents for the early 2003-2004 4.7 and realized I did knock that vac hose off the back of the intake manifold.
It's all back to normal.
Thanks for all the help.

On the subject of finding vacum leaks...
Instead of using any type of liquid a cheap, simple and very effective way to find leaks without any sort of solvent/liquid is propane. They sell actual kits that utilize a small hose and wand that you probe around potential leaks and all you need to to do is listen for an RPM increase. But you can make one for about $10.00. Just buy one of the cheap propane torch heads at Lowes or Home Depot and unscrew the burner. Screw it on to your propane tank and open in slightly. It does not take much. Then start your truck and start moving the "torch" around likley leak locations. You can add a vinyl hose and make a wand with a piece of tubing. But if it's for a one time use, you don't need to.
The beauty of using propane is their is no mess and no risk of damaging paint or rubber hoses, wire insulation, etc. And it's no more dangerous then spraying solvent on your engine.
Here is an expensive version of the same principal: http://www.grahamtool.com/vacuumleakdetector.aspx But it's not expensive if you work on cars all the time. A great tool to have.

Sorry to drag up an old thread, but thank you!
Thank you, thank you thank you...
Changed plugs and ended up knocking the PCV hose off the back of the intake and could not find the leak. Actually the elbow was rotted and it split, but it was my problem. I was dreading digging into the truck to try and figure out what I did.
