car isnt detecting misfire

I have had a minor misfire (can only feel low rpms in 6th gear) problem that has slowly gotten worse. Now I can feel the misfire in all gears and all rpms. Problem is, the car is not throwing a code. What would cause the pcm to not detect a misfire? Every now and again it will say random cylinder misfire but never tell which one is misfiring. I have replaced wires and checked plugs. Coil packs or injectors maybe?

I took all the plugs out and inspected them. The plugs only have 2k miles on them, the same as the motor. Hard to tell if it is missing at WOT, and no I do not have egr.
