My 6.7 had been running fine and today the emission system screwed up. I was 5 minutes away from my new good dealer. They took it right in and fixed the code. I t had went into Regine and screwed up. Dang when this happens it want run worth a crap. Now it seems to be fine.

 

how many miles did you have on it kev94mx. Just curious...

 

1400 miles. It said system ok the entire time. It acted like you had water in the fuel when it was cutting out. I hope they soon make something to bypass this stuff soon or plan on plenty of visits to the dealer.

 

oh god, im at 1350 miles now!!!!!!!!

 

I'm at 2850 and haven't seen regen yet, but I drive the pi#% out of it every other day for about 55 miles on the turnpike. No muffler and no codes as of yet, finger crossed...

 

after 800 miles I started pulling alot. I was pulling about 9k when it happened. It sounded like the 2 generation engine when it messed up.

 

When I first got my truck, it was super quiet when running, even if you were standing outside. Almost sounded like a gas engine, but not quite.

Now, I have 2300 miles on it and it sounds a lot more like an 05 or 06 5.9 when idling. Don't get me wrong, I actually like it better since it sounds more dieselly, but is this just normal as it breaks in or should I be concerned about anything? No codes or lights of any kind, seems to run fine.

 

I loved the sound it was making but it wouldnt run Today I was on some very steep hills pulling and that dang exhaust gets hot. I hope it burns the guts out those crappy pipes,

 

I have nine thoousand miles on mine now. computer says I've only done seven regeneration cycles. but I know I have a cracked dpf or cat.. because the truck smokes... which I don't mind. I know it won't clog up if its not stopping the soot. and no codes thrown. so I'm not going to replace the cat or dpf

 

How do you find out about how many regens it done????

 

go to a dealership, and have them hook up a starscan to your truck. It will show how many regens it has attempted, how many were completed, and how many failed... along with a "desired" ammount. it "desired" 90 regens. Had 7 completed successfully, and 0 failed.
