03 f250 6.0 blowing white smoke need help

[Powerstrokemoncton]

hi
i have a 03 f250 6.0 2 weeks ago had extreme power loss changed fuel filters and icp sensor was showing bad so it was changed to. took it for a drive shortly after started blowing extreme amounts of smoke. This happens at idle no smell of coolant in the exhaust. unplugged icp sensor did not make any difference. Any ideas would be greatly appreciated as this is my work truck.
thanks
David
