i noticed while i was driving the other day, that all of a sudden, when i accelerate my engine will bog down, kind of like it would if you put a low octane gas in it, it started doing that after i put the holiday 93 octane in it. I usually run superamerica 92 octane but i was almost out of gas and holiday was right there... i figured I'd run the gas out of the tank and fill it with the 92, but after i did it, it still does that. any idea's?
 
Checking for codes is a good place to start.

Have you checked plugs and wires lately. Water in gas maybe try putting in some heat.
 
plugs are probably fouled out. then you can't get a strong enough spark to ignite all the fuel so the car bucks and shudders.
