this code recently came up on my car after it sat for a year. My mechanic suggested that I put premium gas in it and see if it would clear up. So the next day after filling up I started a 500 mile trip to see my family in Tennessee. Everything went fine, until I was leaving Nashville. It started acting like it was stalling out, but then didn't. I made the last 50 miles of the trip without any problems, but now I'm concerned that I may have a faulty o2 sensor. What do ya think?

Shorted heater circuit is most likely the o2 sensor. Test (with atest light) for 12 volts at the plug for it with the key on, just to be sure itis getting power
