I just had the same problem on my Tacoma. I ran it through the scanner and it gave me the O2 sensor code. I checked some forums and they all recommended to clean the mass air flow sensor. I checked it, and even though it wasn't dirty, I cleaned it with some mass air flow cleaner (alcohol will do just fine) and the sputtering went away. I also changed the air filter while I was at it. If you have any more questions, feel free to ask me... ElMaliante3701@hotmail.com. Good luck.
