Having some issues

[Parker_]

So recently my truck started stuttering on the highway when I stay at a constant speed with cruise or with out still does it . It starts to stutter like jump forward ish . Changed fuel filter cleaned air filter when I opened it it was sitting in there in attached so I got maf sensor cleaner and cleaned that as well,still does it . No codes being thrown . Also I know everyone hates black smoke blah . But my truck would throw a good little cloud upon standing in it and immediately clear up . Well I noticed it doesn't do that anymore and it not seems kinda hesitant . Kinda like a little sluggish on spool up . Any ideas or directions to go from here ? Kinda don't know where to go

Not sure if I can or not . I know I can get m.a.f readings from my efi live thing, would unlike me to get those and also fuel psi ? Can I get those while driving ? Meaning of I leave efi live module plugged in ?

How does the dsp5 switch not working make it stutter or jump forwardish?
Sounds like what mine does at light throttle, usually does it when idling forward at a stop light. I've always convinced myself the FRP is on its way out.

Mine does that sometimes, that's with a new FRP. I think what the OP was stating was that the fuel housing was shot, but at the same time, the DSP5 switch wasn't working. More as a side note.

Ya it's weird. It kind of lopes and bucks during an idling roll. Like it doesn't know whether it's coming or going

 

[ieetgluu]

When it happens at interstate speeds I either have to throttle it or let off completely to make it stop

Do you know if it has the updated injector plug ins?

Yes that's exactly what I was saying thank you
