I am halfway convinced that my check engine light came on because of poor fuel quality (I never fill up at Murphy USA/Walmart...but this time it was the only thing around). A few days later my CEL came on and has been on ever since. Also, for a couple of months, anytime we fill the car up with gas (but only when we fill it all the way up) the car kind of jumps a few times when accelerating, and then it clears up until the next time we completely fill up. Anyway, I checked the code out and it came back P2066-Fuel Level Sensor2 Performance. Can someone tell me what this means and what needs to be done to fix it, if anything? Thanks!
