And no check engine light? When my 05 5.4 did this it was bad coils...

Nope. Runs real good. Allot of power. Felt like when I first got it with 100k on it. Now there's 141k

Darn. I don't know bud, sounds like mine did before my coil problem, at the beginning. I'll keep an eye out for similar problems. Best of luck

Pull your air filter drawer out and check the foam gasket. Mine was gone, replaced it with foam door gasket from home depot. worked like a charm.

My ford tech buddy told me to try checking my engine and trans mounts. But I would think that if they were bad the motor would be shakin all the time and while driving.
