I have a 2011 Ford Fiesta. 43,000 miles. The check engine light came on 2 days ago. I had a diagnostics test ran and the code came up as 303 cylinder 3 misfire. It studdered and lost a bit of power at times but also drove good at times. Yesterday, the check engine light remained on but drove good all day with zero issues. Today, after scheduling an appointment with my local Ford dealership, I started the car and the check engine light did not come on and the car drove good. I did fill up the gas tank the same morning, prior to the check engine light coming on and before the studdering/power loss. The car is near "E" now. Could it be that I had a bad tank of fuel?

Bad fuel could cause the issues your having but wouldnt just target cylinder 3.
