Do you have headers? I agree its seems kinda odd that they would go at the same time but it happened to me. I replaced them and didnt get those codes again.
Reset the codes, take it for a drive, keep an eye on the light, and plug in the obd so you can actualy see if they set at the same time or not.
But either way if you get any of those codes, in my experience, its then time to replace them.
