i was cruisin home today and all of a sudden my gas guages goes for a poop and obviously im thinking to myself, great, the one time i fill up with mobil instead of shell.

so i check my error codes and it's got P0131 posted, the 02 sensor code, which i get from time to time, usually after some aggressive driving, anyway i reset it and the guage goes back to where it should be.

anybody else find this is a little odd? considering the two have nothing to do with each other.
