3.o blues

Need some help here. 2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higer rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to help for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on. Any ideas from those whom are much smarter than I am?

When an engine is put under load it increases the the resistance on the plugs. If there is a weak plug(s), bad wire(s), bad or cracked coil pack then it will miss.

I am guessing but I would say a bad coil pack or it could be the PCM.

Not being able to get any codes from the PCM is a bad sign, does your scanner work with other vehicles? You could have a blown fuse on the DTC connector(it's often on the same circuit as the cigarette lighter) or you could have a PCM problem.
