I was driving home today (96 gxe) and I glanced down to see that one of the malfunction light indicators was on (It's on the bottom right corner, labeled as 'CHECK'). I went home and took a look at the manual, it's the MIL indicator. The manual then goes on to describe that it could be an emission system problem, or just air in the gas tank. I checked EVERYTHING and got nothing, any suggestions much appreciated.

 

You have to run the MIL code to see why it tripped...Did you get gas cause all it could be is that the gas cap wasnt tightened all the way and tripped the computer to a small leak

Ok, so I just ran the code and got a Front/Left Heated O2 Sensor. How should I go about fixing this? (Dealer, etc..)
