Question 2010 6.4 missing or rough @idle

I've been doing a lot of reading through the forums but haven't found any help, so this is what's going on...

First off its got 9,900 miles on it. I've changed the oil twice using Ford Powerstroke oil. Have not changed fuel filters as of yet. NO mods... I've got a Superchips programmer but I'm afraid to put it on for fear of screwing my warranty.

I've yet to have ANY issues with this truck... although I can't remember the last time it did the regen... (that's got me a bit worried.) I've run Lucas in every tank of fuel.

Went out today and got in, started it up and it ran like $hit... felt like it was missing / sputtering at idle. Gave it some pedal and rpms climed but sputtering remained. Drove the truck down the road... running it pretty hard.... and it cleared up some. Truck is still running a bit strange and I feel a slight power loss.

Morning bump. I hope someone chimes in soon b/c mine is doing the same thing just not as bad. When I'm in drive but stopped its like it almost starts doing a "lope idle". just started this morning on the way to work.

With less than 10K on the clock, I'd go to the dealer.

^^^ What he said...

These things can be kinda troublesome to diagnose without the right tools, and most guys don't have the right stuff at home.

Thanks for the replies. I called around today for pricing on changing the fuel filters. Ford wanted $125 installed for both filters. The local quick lube chanrged me $89 and used motorcraft filters. I know it's only $35 difference but hey... that's 35 bucks man! I looked at the filter that was pulled from under the hood and it was pretty much clean. There was a light colored ring towards the bottom half of the filter but they told me that in comparrison to most of the filters that they had pulled from the 6.4's... this was "like new". Truck is back to normal now... although I drove 2hrs to work today (b-4 filters changed) at interstate speeds and it cleared up so I'm not sure what the hell was going on. Still has yet to go into regen... and I really can't remember the last time it did. I wish I had the option to put the truck into regen myself. If it wouldn't jack my damn warranty.... I'd have that freaking exhaust cut off and my tuner on it... but I'm too SCARED

Thanks again fellas...

I have a 2010 that idles rough sometimes as well. It has also died like it is out of fuel 2 times and had to be towed to the dealer. 5700 miles on it.

Has everyone been draining their HFCM on a monthly basis? Any water detected? Sounds like bad fuel if no codes are being thrown.

The fuel going into the 6.4 must be pristine.

Still no more issues since that morning. But the truck has still not gone into regen. So I'm getting a bit scared about this . It's running just fine but no regen in at least 2500mi (I haven't seen it come up on the dash read out, nor felt it run bad besides that morning). I wonder if the 'Lucas' has anything to do with this. Anybody heard of any issues with running Lucas in the 6.4L?
