My money is on the gas cap also. My gas was screwed in all the way and I would still get a SES light. It wound up being the cap itself was cracked I replaced it and I've never had a SES light again. Just something to look at OP.

^This. Happened twice to me, first time was just carbon build up from not being driven much. Nothing a bottle of fuel stabilizer and driving it more couldn't fix. Next time my driver side cat failed so I gutted them. Could be an O2 sensor as well.

Check out mine imo it looks alright what do you think should i replace it cause the ses light came back on again ever since i didn't screw it back in properly
