Bad fuel?

My truck is missing a little bit on acceleration. I suspect I got some bad fuel. Not getting any engine codes...? Is that normal? If it is bad fuel, should I drain the tank or try and just let it burn through? I put some heet in the tank and that helped. Have run about 3/4 of the tank out and refilled with high octane.

Is it a "miss" or is it just running crappy? If it really is a missfire, then check the plugs. See if one looks different. Then check the coils and wires. If it's running crappy it could be alot of things. Dirty throttle body will cause it, and I have had that come on pretty quickly. Bad gas of course will do it. Usually a true misfire will throw a code.
