    "gutting" the cat was not a good idea. The cat is not gonna throw the same code. Some things to check would be, an exhaust leak, Cat. Converter (is it OEM?), and Down stream heated O2 sensor.

    yea its the oem cat. and i honestly dont care about the check engine light being on. i just want it to stop sputtering, it did it before and after i did it to the cat, and plan on getting a catback in the near future thats why i did it
