Stuttering help

[dg7.3]

I have a 99 f350 that I just bought about a month ago it has about 187k on it and a fresh built tranny. But over the last week it has developed an occasional stutter when i am running at low throttle going through town or something almost feels like a skip and when i first get on the throttle to pull out of the drive it does the same thing but as long as i'm on the throttle at least 1/4 or more it runs smooth also when i first start the engine it idles kinda rough to begin with but i have no ses light. i'm thinkin maybe a sensor because it's sporatic its not a constant thing but i'm not sure any help would be greatly appreciated

perhaps a loose wiring harness under the valve cover? or, a "funny" injector? or ???
I would start by scanning the 'puter with a high quality scan tool such as a Snap On. Let us know what you find out.

Hey no problem maybe someone will reply now lol i changed the cps on mine today and didn't change anything. the problem seems to be getting worse though hiccups have gotten harder and more often no smoking or anything though so who knows

yeah...mine got worse as i drove it home...its like the same sync rattle as a normal idle but loud and clanky sounding? its like stuff is mashing up in there. i dont like it though

my 2002 F250 7.3 is doing same thing and i have only had it for 2 days. starting to get a little aggrevated. if i find something out i will definately post it up here. 3 mechs gave me 3 different problems. fuel filters, cps, and last but definately not least (most expensive) fuel injectors...
