I have an 05 f-250 with the 6.0 in it and it has been acting a little funny lately. Every once in a while it will lose all its power and i have to put my foot in it to clean it out. when i do it blows alot of wjite smoke but then clears right up and runs fine. and suggestions on what it can be.

 

are there any signs of coolant puking, have you cleaned your egr valve, are you runnning a programmer, need some more info man and you mite want to repost in the ford 6.0 section youl get more responses

 

yea i just reposted in the 6.0 section but yes it has a superchips tuner in it and i cleaned the egr valve a couple months ago. and i havent noticed any antifreeze leakin out anywhere cause the only time it blows the white smoke i when its losing the power any other time it doesnt blow any
