Infiniti I35 catalytic converters
I have a 2003 I35 with 361,000 miles on it and I would like to know if there is more than one converter on it and are they hard to change or does it need to be done by a service center. The reason Im asking is the check engine light has been on for awhile and I changed out the two bottom O2 sensors but the light came back on after a few days so Im assuming the converters may be stopped up with that many miles on the car any suggestions?
