Today I filled up and when I restarted the engine I got white smoke, no power and rough running. Had to replace the EGR cooler about a month ago. What could be the problem? It ran just fine before refuel.

 

try unplugging the egr valave see if it gets better.

 

My 04 did the exact same thing and it ended up being my EGR Valve. The dealer cleaned it and it ran fine for about a week and started doing the same thing. They ended up having to put a new valve in and haven't had any problems now for the past 3 months.

 

I was stuck in Kingman AZ for a week while the local Ford dealer replaced the oil cooler which was the root cause of the trouble. When the oil cooler went bad it took out the EGR cooler and the turbo charger as well. This is the second EGR cooler to go bad. Needless to say I am not too happy with my truck right now. Iam on a two month trip pulling a travel trailer. It is difficult to have convidence in the truck. At least the warranty covered the damage.
