I just changed the fuel fillters and oil on my 2004 6.0 power stoke.Now it has lost power and blows tons of white and black smoke. Any one have any ideas to this problem?

Could be you did not get the new "o" ring in correctly and it is leaking.

Black smoke is usually a sign that there's too much fuel, not enough air or injector pump timing is off. One of the most common causes of this condition is an air inlet restriction--the cause may be a dirty air filter, collapsed intake hose, or exhaust restriction.

White smoke usually occurs when there is not enough heat to burn the fuel. Unburned fuel particles go out the tailpipe, producing a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather, until the engine warms up. Bad glow plugs, or a faulty glow plug control module, can cause white smoke on engine start up. Low engine cranking speed can also produce white smoke. If white smoke is visible, after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing, or a worn injection pump. Low compression can cause white smoke, as well as air in the fuel system.
