Fellas,
I have a 2012 Ford F250 6.7 powerstroke. Truck has about 30,000 miles. Has been completely flawless and has exceeded all expectations. Well....I am experiencing my first hiccup.

I traveled yesterday from Louisiana (flat land) to North Missiouri. While going up a slight grade, running about 50 mph, 1000 RPM, 10PSI boost...truck started bucking and sputtering with weird sound coming from around the air box. It felt just like you had a blow out on the front right tire. My initial thought was i just had a blow out as the truck hopping. Well, once i let off the throttle everything went back to normal. It did this about 5-6 more times on the trip. When it would start doing this I would just let off the throttle and everything would go back to normal.

I've read a good a bit on this 6.7 and appears that turbo issues are common.

Being optimistic, I am hoping this is something that can be fixed easily.

Again, have had ZERO problems with this truck, runs great, and even now on the trip runs fine but now we have this intermitent issue that i DO NOT LIKE.

I am very deligent in taking care of my equipment, have not abused this truck and all maintenance is current (actually a bit over kill).

Please give me your thoughts on what the issue could be.

Thank You

J

 

How far apart were these episodes?

My truck did the bucking 20/30 seconds right before a regen would start. There is a tsb for this I believe.

 

did it 5-6 times over about a 3 hour period on the trip....noticed mostly when was going up a grade

 

Hmm, so it probably wasnt regens causing it...

 

Here's the tsb...

Thanks for the info.

Refresh my memory, what is the factory powertrain warranty on these trucks, how many miles?

 

5/100 miles

 

This sounds like an issue I had. This seemed to fix it: http://www.fordservicecontent.com/pu...sb13-04-03.pdf

 

Well that makes more sense, good call.
