   This goes along my with my O2 sensor problem. I just remembered...
   
   Alright, so I have been using 89 octane for almost a year, I just came back from a road trip out in the sticks. The only gas station around was Citgo, they ONLY had 87 octane. Could this cause my O2 sensor (CEL: P0137) to fail? (like stated in my thread below) Switching gas? I had a quarter tank left of 89 but needed to fill up before I hit the highway with nothing in sight for miles.

   I've done this many times. I seriously doubt that's the problem and it's just by chance you switched gas.

   I seriously doubt that would be the problem, as I have driven across the country twice and used 85.5 (Montana), 87, 89, 86 (New Mexico), and even 93. It might have happened, but I highly doubt that...
