Sputter & Hiccup
Hey Guys need your help.
Have a 2004 King Ranch 4x4 6.0 with edge juice & airaid intake. Recently took trip from Dallas to Il. Ran fine on the way down however, on the way back it started sputtering. Had it on auto pilot at about 75mph and while pulling a hill it started missing and sputtering to the point were it would downshift to keep the speed. Did this all the way back to the house (500 miles). The truck has recently been sitting for about 6months and only driven a few times prior to trip. |

more than likely you have one or two injectors dropping out. that said, does it run good cold and then bad after it warms up. does it start ok cold....hot. and if it sat that long, was the rough running symptom right after it started after sitting? there has been some high pressure oil system o ring failures (usually runs rough hot, and will not or starts very tough hot) and also, i have seen a few on the lot, low milage vehicles usually, that sit for more than 2 months without being started, and the valves stick. upon start up with the stuck valve it bends the pushrod, then misses untill the pushrod is replaced. most of them were just due to sitting, although i have replaced one head do to a sticking valve. as i said before though, i would almost put money on it you have a bad injector.

Thanks for the help.
Seems to start fine cold or hot. It ran fine all the way down to Il. Just the problem on the way back. |

90% sure, based on what you told me, that it would be an injector failure from what you told me.

this is a old forum i know but my 07 6.0 has a sputter now after being gelled.... it ran fine for a week after we got it started and ungeled we changed the fuel filters and everything when we got it going after being gelled its been a week and today its starting to do an awful stuttering.... what kinda repair bill am i talking for an injector? my problem seems to be less than his it runs decent enough but i know something is wrong the sputter is through acceleration and at higher speeds.... never at idle.... could it be a fuel pump pressure issue? or do you think its a injector? it has not sat for more than a day in its life.... and has never been ran hard im the only driver.... any help would be appriciated

I just bought an 04 excursion with the 6.0 1 week ago. It seems to be doing the same thing, but it's not all of the time. Seems to do it after the engine has been off for around 1 hour. Then today it started putting out a little black smoke. I heard that it may be an EGR Valve or something, could that be?

Same issues
I am having a similar problem with my 03' it idles fine and when you accelerate it coughs and stutters, just feels like 1/2 power then it will yake off. I thought it was gelled fuel and changed the filters and it made no difference. I also de-tuned it and it was a little better but very frustrating. Any ideas? CPS or EGR?
