What do you guys think? Just change o2 sensor 10k ago. Nothing leaking or noises. Side note I just bought gas from so hole in the wall gas station in the middle of no where. Thank you.

check your gas cap.

Post-up the code too. Most likely happened to someone else already.

2nd that. Could be a lot of different things... Go to your local auto parts store and have them run a diagnostics and report back with the code.
