Have the codes pulled again. The codes are your best clues for getting specific help.

Aight ill head back to autozone and get a code checked, and ill update with codes
Hopefully i can get the CEL codes fixed!

maybe it's so simple that nobody has mentioned it, but did you disconnect the battery when you swapped the O2 sensor? because it you did not disconnect the battery then the ECU will keep the trouble code in it's memory, even if the engine is no longer throwing the code. to get rid of all stored trouble codes just disconnect the battery for a minute or so, then reconnect and check you check engine light again.

okay Ill try that too thanks

P0420 is the code from Autozone
Seems like it is the Catalyst converter
