Missing and sputtering

[Lil-Pony]

I have a 98/99 ranger 3.0 that I've put a new coil pack, plugs, wires, and cam position sensor on and it still idles rough when cold putters on acceleration sometimes and throws miss codes every month. Suggestions

Which "miss" fault codes does it generate?

Has the fuel filter been replaced recently? A lot of people have had injectors go out which can cause a misfire/vibration/loss of power. The fact that the idle issues go away when warm could signal a vacuum leak as well.

Cylinder 6 was last month. And ive lost track of the others.

Today was cylinder 3 but that may be due to me playing with the plug wires while the motor was running.
