Notick01 you probably have a sensor that is messed up and when you went and did that you actually probably just made the problem worse sensors are very sensitive like if you have it a hole in your exhaust either before or after the O2 sensor that can make your car run rich or lean depending and if it's before or after the sensor when you try to bypass stuff like that it doesn't really help
