Slight stutter/rpm drop

Ok so I've already put new batteries in the truck because the PO had the wrong size in. Occasionally I will see my lights slightly pulsing however I'm not sure if it always since it wouldn't do it this evening. I had my neighbor throw his meter on it and the alternator is charging at 14.8 to both batteries.

Ok I have no idea of any of that is relevant to this part.

Ever since I've had the accelerator pedal sensor replaced a CEL comes on for the first minute of running the truck and then clicks off. When it does this the rpms fluctuate app 100 rpm. Now I've been to 2 shops and 1 dealer to pull codes both while that light is on and while it isn't. There are no codes.

That also doesn't bother me so much because it goes away right away.

Here's the kicker. At idle the truck runs smooth as silk. Under hard acceleration it's almost always fine with the rare hiccup. What's bothering me is that while maintaining any speed 35,45,60 anything...you can feel the rpms stutter. It's only about 50-75 and most of te time the needle never moves. However occasionally you will see it flutter.

I used to think it was just my foot bouncing on the pedal since ever diesel I've owned has had a sensitive pedal, but now I'm sure it's not.

I've checked Ll my battery connections and grounds. Also tested the alternator in park at idle and 1500 rpm. Tests fine.

Now this doesn't feel so bad that I think the trucks gonna just die but I'm overly sensitive about my truck.

Now I don't know I'd any of these things I've listed play a roll but I'm just rambling.

What do you guys think? I wanna make sure this is safe for my wife to drive while I'm out of town.

Thanks in advance
