Intermittent microsecond “stutter”

[william wixon]

This is really important, I’ve been putting it off for a very way too long! I really need help with this.
I don’t know what better word to use than “stutter”. I’ve put an OBD II reader on it and it’s not throwing any codes. I can’t really find any correlation to any situation or action, but if there is any, it might be on acceleration. If I would have to guess I think it’s some kind of electrical issue with the injectors. It’s really difficult for me to tell how many cylinders don’t fire, but it feels like one or more (ALL!?) cylinders don’t fire for one revolution. It’s a very quick “stutter“. Definitely feel it in the truck. I’m very scared, very concerned my truck is just gonna stop running one day on the highway. (actually the Taconic, it’s been rated one of the most dangerous roads in New York state. Very twisty turny, very narrow, sometimes no place to pull over at all.) Really need help on this, terrified desperate. I do not want to take it in! I thought maybe it was a fuel problem, I thought maybe the fuel filter was clogged I replaced the fuel filter and crossed my fingers but it’s still happening

Sounds like a misfire to me.Check and replace spark plugs ,then open the hood at night,with motor running and see if there is any arcing from the wires or boots .
Also listen for a slight "tick" which sometimes accompanies a spark plug wire breaking down.
