engine runs excellent, no skips, plenty of power, no smoke no noises.
it has six new plugs, injectors and coils and the code still comes back.
the light does not flash and there are no issues whatsoever with the engine running.
the light has been coming on for a while, long before the parts were changed.

misfires are very hard to diagnose. your cheapest option is to have a mechanic use his scanner and see If any sensors are messed up causing it. you can check for low fuel pressure and vacuum leaks, sensors bad can cause it or basic engine problems.
