The reason for the problem can be faulty fuel injectors, clogged air filter, faulty ignition coil, and many more or none of these. These are just assumptions for the problem. The real problem may be something else, so I would suggest you to get your ride checked for the error code and then update your answer indicating error code.

Would need my head under the bonnet to find the answer ,from your description it could now be a injector who knows but take the plug out and see if its all wet and black then go from this point as fault could be a coil pack /valves or fuel injector but as you havent stated year then again it could have a coil on each cylinder or a remove coil pack as you stated it has HT leads (wires)

OBDII code P0306 describes misfire # 6 cyl or ign misfire, wires are new, coils (3) are new, rough idle on acceleration possible bad fuel injector or ???

I noticed that you didn' t mention the plugs. I'll assume that if you did wires and coils that plugs are also new, so I would say that you need to check the injector on that cylinder

Same issue with the rough idle with a warm engine 4.0 Ranger

i would think a plugged fuel injector on # 6 cylinder could be the problem,or a big vacuum leak at that cylinder
a valve burnt/stuck could be but you dont see much of that anymore
could be coolant leaking into cylinder from leaky haed gasket but you would have to add coolant every so often
i would check #6 cyl. spark plug after driveing around a while if it looks new, ie no deposits on it then an injector would be what i would change next

It's either a carbon tracked spark plug & boot or a faulty fuel injector.They have alot of issues with the ecotec engine with idle concerns due to injectors.If it misses under a load it's more than likely a saprk plug & boot concern
