Car: Loud Sound, No acceleration?

I own a 2008 Honda Accord Coupe. It is 200 miles from hitting 100,000 mi.

I was driving it earlier today and it drove great. But then I stopped to get gas, filled it with premium as normal.

As I pulled out of the gas station and hit the gas pedal, my car sounded like I just put a ridiculous muffler on it. My car had a deep growling roar to it's acceleration now, but my power was bled. It takes forever to speed up and when I punch it, it doesn't even try to shift. (It's an automatic)

I now have a "VSA! Is OFF" light and check engine light. Anyone have any idea? Bad gas?
Added (1). Yes, I'm positive it was 93 octane premium fuel.
