Explorer Trembling Help!!

[Shawnb231]

I have a 2006 Ford Explorer XLT, all of a sudden I noticed it started trembling when stopped, in gear and in park.
My rpms do not fluctuate at all and the truck seams to run fine. I took it to the dealer where I bought it and they hooked it up to the computer and saw nothing out of place. I have no check engine light no service codes vacuum leaks nada.
Motor mounts were checked and all in good condition. Its has a Brand new air filter just changed the oil. Totally Lost. Any Ideas?

If it's not a vacuum leak this comes to mind:

Ok will give that a try, also could a bad pcv vavle possibly cause it to tremble?
