Default vibrating at idle

08 screw 5.4l with 29500 miles

When stopped at a light (or even when I first start the car), the truck vibrates a little. Nothing MAJOR, but enough to annoy me. I'm getting my oil changed and transmission flushed tomorrow for my 30k maintenance. (I'll change the air filter and fuel filter myself).

Any insight is greatly appreciated. Thanks


**I tried a search, but 99% of the vibrations issues deal with driving (which mine does every once in a while when I get up to highway speeds).

ya mine vibrates like a bastard, only when its in drive or park, when stopped...if im stopped at a light and put it in neutral, it wont do it...but ya, it is only when its not warmed up
another one i test drove before i bought mine did the exact same thing.
i dont think its a problem but its annoying as ****

Check the elbow at the PCV valve. Have been known to crack.

Positive crankcase ventillation. A system used to vent the crankcase pressure back into the intake instead of into the atmospheir. The valve separates oil particles from the air.
