LACK OF POWER

1990 Cadillac Fleetwood

Engine Performance problem
1990 Cadillac Fleetwood V8 Front Wheel Drive Automatic 74500 miles

I have a 90 cadillac fleetwood that is losing power very badly. I've changed the plugs, wires, rotary button, fuel filter, and even put on a new cat converter. The car has no power up hills it actually goes down in mph instead of up. What could this be?
