I have a 2008 350z, code came up catalytic converter , they replaced it. Within one week the same code came on again? Does the car have more than one converter? what else should they look for? Thanks

Hi there there will be only one converter, if it has a down stream O2 sensor, ( behind the converter) this may be faulty, this is only used for calibration purposes and may be sending false information, otherwise get an exhaust gas test done and check for high hydrocarbon levels, this can be a leaking injector which can cause a converter to overheat, start here.
