Sputtering in the rain

[Illini]

My 2010 6.4L F350 has only 7000 miles on it. Routinely, when driving for a bit in the rain, the truck will start "sputtering" under acceleration. It's most obvious when trying to pass or downshift, going over 2500 RPM. I cannot pull my camper in the rain like this. Dealer could not recreate problem and found nothing wrong on the computer. Told me to stop driving behind 18-wheelers. I said, "i can't pass the 18-wheelers if my truck is not accelerating (duh)"!

Any suggestions? or others with similar issue?

much appreciated! I'll bring this TSB into my dealer. Just experienced heavy white smoke the other morning after overnight rain. But, this TSB is for builds before 10/2008. Mine was built 01/2010.

I just had mine changed last saturday for the same reasons but as you stated my truck was 03/07

It is possible to get water in the airbox. There wouldn't be any evidence left after because it has a drain, but that could explain the sputtering.

I was towing my camper up a steep hill this past Sunday in a friggin down poor. I was at full throttle and I thought the wheels were spinning and cathing because it rved up and down a couple of times. I could consider this "sputter" but I am not sure as it was a really steep hill and an 8200 lbs. trailer. I thought there might have been white smoke but it was raining so hard I couldn't be sure. I have been losing coolant with no leak so all might be related. Build date is 10/07.

So should I change-out the filter box (considering an AFE stage 2 that pulls air from top of engine compart) or will that cause other problems? I have read that it can cause the fuel-air mix to run rich, which can cause the DPF to regen much more frequently. Is that true?

I live in MIAMI, & it has been raining every day for the last 5 weeks, In the 2 years I've owned my truck it has only sputter once & it did it only one time.

I am having the same problem with my 2008 it have been into ford 3 times for the same thing in 2 weeks they can't find the issue. I took them the intercooler TSB and they told me that this does not happen in our area its not humid enough so warrenty would not cover this in our area, but in the last 60 days it has rained at least 30. Ford aslo told me it is normal for the 6.4 to blow white smoke and sputter. WHAT THE HELL??? I have a DPF+CAT delete they are trying to pin it on that, but you know as well a i know it has nothing to do with moisture in the intercooler. So what do i do? Just take the cooler off myself and see what moisture is in there??? HELP ME!!!!!
