The 5.0L was prone to carbon build up on plugs if not driven hard occasionally out on the highway, and would cause the symptoms you describe. Before I got too carried away with replacing parts, I'd pull my plugs and inspect for carbon build up on any of the plugs. If you find one or two, clean them up good, or replace them & test drive it. Let us know results.

Car "bucking"

Are you pulling a trailer or have a heavy load - you should not drive in overdrive in those conditions. You will eventually ruin your transmission.

My 2002 Mercury Sables gives a "bucking" sensation

Yes Brother, I know that experience. Have a computer test done to find which cylinder is misfiring and replace that fuel injector. It's gone dead and we call this a dead cylinder. Seems like it runs fine, until you hit overdrive. Then it feels like you're running on one square wheel. A steady thump.

Truck runs rough

Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.
