Well, you really have to think of it this way.
Missfire is USUALLY caused by 2 things.
Spark or Fuel.
So do the easy things first.
Check your wires, cap, rotor, plugs and lastly COIL. Coils can go bad so thats one thing to check.
If its missfiring on WOT, fueling could be something too if the car is starving for fuel or getting too much. Check the color of your plugs. fuel filter, fpr, and finally pump.
It may be an O2 sensor, but unlikely, the car will run rich if the o2 is dead but ive never seen it missfire, but all cars are different. Good luck with your problem!
Its one of those things
