2002 4.6 AOD 2WD. 80,200. recently replaced plugs, and fuel filter. had vacuum hose replaced not long ago. Idles smoothe, engine runs strong, but when I 'Get on it' it just seems to be lacking somewhere. Any pointers towards getting back lost horsepower?

Foul/defective spark plugs.
Open spark plug wires.
