Been there, done that.

It is your oxygen sensors my friend.

Change them and I'm 99% confident it will fix the problem.

If not, start to look at MAFS and coil packs etc.

Also, and for the benefit of everyone else here, I will share a tidbit of bad advice I received from searching on another forum. Someone suggested unplugging the MAFS to see if this prevented the car throwing up codes, and if so, it is the MAFS which is faulty. BAD IDEA. I unplugged it, car ran just fine but very down on power. When I replaced it with a new MAFS $500 later, the codes came back after 5 minutes. So all I could deduce from that is the car just does not throw up codes if something is unplugged, whether the component works or not.

Good luck!

Well. I guess that would lead me to my next series of questions. How many o2 sensors does the car have? where are they located? Is there anyway to test if there good or not? If I do need to replace them is there any certan type I should get? Thanks for all the help btw y'all have been great!
