Default Need help!! Demon codes

d help!! Demon codesWell I have these codes I cannot get rid of.. 02 sensors work are good , new battery , 02 extension are not burned..I can ride for about 3 to five min then the cars start to shift crazy,02s work then stop working..at WoT the car sputters sooo bad. makes trans lock up fast then shudders badly.. at idle it’s real rich ... seems like the car started to run like this after I flashed a new hp tuner file not saying that may be the cause but it hasn’t been the same since that flash.. I’ve also reflashed the ecm stock then reflashed tune but still throws these codes ,same issues.. has anybody had these issues I’m mentally drained on this lol...

Did you happen to skip the key cycle after flashing that file?
