My truck started sputtering a couple days ago. I thought it was running out of gas. It idles fine, and I have no trouble when motor is cold. Once warmed up it starts acting up again. It gave the O2 heater code and I replaced the sensor this weekend. It seemed to help some, but not completely fixing the problem. Was told to replace catalytic converter, but wouldn't it throw a different code if the catalytic converter is bad? What is my next step to finding the cause of this?
have the same problem?
