2-3 TIMES A WEEK ill be driving my 08 f250 D ill be goin hyway speeds butt wen i turn then try and get back to hyway speeds it bogs down and puffs blue smoke for 10 sec and stay at 2500 rpm after 10 sec its totally fine ????????????????????????????

any help thanx

 

Was it damp when it happened and are you sure it is blue and not white smoke? There is a TSB for this.

 

no for sure it was blue and this has been goin on for a month and a bit so its had every kind of damp dry hot cold weather

 

Blue smoke usually indicates oil being burnt, but I don't know what would cause that on a truck as new as yours.
