Could be leaning out under load, have the codes pulled and see what they say, as you had a flashing light it should have stored it in memory.

I already replace the distributor cap

First off an 04 doesn't have a distributor cap, it has coil packs. So there's no way you could have replaced it. You might want To find out where it's misfiring and replace the coils on that cylinder
