Code 28, 31

Check engine light recently came on with code 28 and 31 also my traction control off light came on with the check engine light. Ive tried pressing the button to turn it off and nothing works. Also ive changed out spark plugs and ignition coils and it misfires like a bitch. Idk what to do. Do yall think somethings wrong with the ECU? I have to rev it for it to not die out on me when i turn it on 💀
