Well. Not exactly, bright boy.
Anyway, I took my truck to get it serviced. It turns out one of the bolts that holds the exhaust manifold to the head is broken (like someone else so eloquently suggested above :) ). As a result, they are replacing the manifold, as it might be warped, and are having a heck of a time getting the remains of the broken bolt out. As of this afternoon, they were putting something (probably penetrating fluid) on the bolt to (hopefully) loosen it up so they can try again to remove it tomorrow.
Fortunately, my extended warrantee is covering it (2006 with 98,500 miles). Phew!
We'll see if that solves the vibration problem. My loose heat shield was not the culprit, as I and other bright people in this forum suspected, even though the vibration sounded like thinner metal than a manifold.
