What's the fix?

Hi! I occasionally have the check engine light come on and sometimes it is accompanied by the smell of gas. Is this an O2 sensor problem? If so, how do I figure out which one is bad?

If this is an 02 TJ you could get the code and podt it up. To get the code: with the engine off turn your key to on (don't start the engine) and off three times relatively slowly. The codes should be displayed in the odometer followed by done.

Post up all that come up.

The smell of gas could mean an issue with the charcoal canister or a bad gas cap. Like JPNinPA said, get the codes and post them.
