Rough running

Yesterday while I was driving the 350 it all of a sudden started running rough/surging while doing 35 mph or so. It lasted about 30 secs. It wasn't REALLY bad but definitely noticeable. My passenger (whom I was driving around looking at new trucks for) said "that didn't seem good."

Anyway, It came and went and never came back. Is this an indicator of some issue coming?

Thanks!

Interesting. I didn't notice if it was regenerating. but I never noticed the hot smell either.

Has yours always done this? This is the first mine has done it in 3,500 miles.

Mine did this at about 3k miles and has done it a couple times. I just happened to notice the regen cycle message the first time or wouldn't have known the two where connected. My truck has other issues so not sure this is the same thing you have experiencing but figured it was worth paying attention too.

You might want to share your build date and any other pertinent info so the folks on this thread can chime in.

My build date was around Aug 8. I see there are a couple other people with issues during regen. Sounds like the truck may be going lean at that time. How long does yours run rough?
