check what??? &nbsp;the brake light? oil light? engine light? seatbelt light? &nbsp;wish i could help you if i knew what you were talking about...

If it's the check engine light, it means there's a problem your ECU picked up. Could be due to your gas, could be something else. Personally, I wouldn't risk it and go get it checked out.

sorry if i wasnt 2 clear...its the yellow light that says 'check' inside the picture of the water tap-looking thing. &nbsp;I just dont get it happening before and it just going away.

Actually u wont get a mil from runnin low octane gas unless its really low octane gas.Where did u get it from. Amoco,Mobil.
What you might wanna check is your gas cap rubber seal, they go bad sometimes and it throws of a mil because of the evap obdII bs.
Get a manual and read the code its fairly easy.
Get some redline injector cleaner it might help if it was bad gas...

thanks daywalker! but i hear ppl talking bout reading the codes, just how exactly do u do that? hope u dont have 2 get in the ECU.. and if its a flashing pattern, the check light just stays on 24/7 with no pattern or anything.

[daywalker]

you take the ecu out its behind the passanger side plastic panel under the glove box right next to the door.
when you take out the ecu u need to find a little screw on it.
next i think twist it counterclockwise and now it will flash out the code, but u need the manual for this
