Can anyone give me any guidance on what to do or any similar experiences. Drove it fine today and then randomly got check engine. It disappeared but afraid it will come back. OBD2 Port reading said error P2237 #07E8 Generic 02 Sensor Circuit/Open Bank 1 Sensor 1. The muffler was just removed and replaced with a new pipe attached to the factory flange with a new set of exhaust tips. Just trying to understand how and why the engine light code was thrown and what the potential is for issues while driving and/or warranty issues. I have my first service end of May and would definitely like to know whether its worth putting the old muffler back on for service or even just put it back on altogether to avoid warranty issues.

Thanks
