go to autozone and get it checked out

Could it just be the O2 sensor?

You can check it yourself.

Jump pins 4 and 9 on the OBD-II port under the driver side dash. You can't miss it look directly to where your right knee would be. Once you jump those pins with a wire several lights on the cluster will start flashing.

You will want to look at the check engine light. 1 long flash = 10 and 1 short flash = 1 when there's a pause between flash sequences that means it's going to the next code. For example: 2 long flashes and 5 short flashes = Code 25.

Add the flashes together to get your code and come back to us.

When u said jump pins 4 and 9 with a wire, is it just a single wire? Can I use my multimeter since its got probes which I think is easier to get to the pins

I just passed the emissions a month ago so it couldn't be the cat converter. I'm down to o2 sensor and a/f ratio. I appreciate all your inputs

Based on this pic, I think its either your o2 sensor or cat.

Is there a way to further find out which one is at fault?

[usedep3]

if you can get a working o2 sensor, plug it in and see if that clears it :shrug:

I might just have to check autozone's return policy lol. Thanks

They won't accept return on electrical components if installed. Our wideband o2's are pricey too.
Maybe it was a fluke? Reset the ecu. If it comes back there's an issue. You said it came on after some spirited driving? I would flog it a little more like a 5-10 hwy ride and get some of that junk burned off your cat. Disconnect the battery for a few. See what happens a after that. If the light comes on right away you know there's a problem.
