P0430 code - 2 identical codes in a 2004 Toyota 4runner v6.

Question

P0430 code - 2004 Toyota 4runner v6. In getting too many varied suggestions and not sure if a 4runner solution is same as for another model or make. Parts store put computer on it and got 2 identical codes - p0430 - do I need to replace o2 sensor bank 2 down stream, do I replace just the catalytic converter on drivers side or both. The oem part is more money than I have, what would be the best aftermarket part/make for this. Any help would be greatly appreciated and hope I can return the favor somehow.

Answer 1

you can try to do an intake flush and use 91 octane fuel from shell along with a good fuel system cleaner, its worth a try.

aftermarket catalytic converter are cheaper but they dont last as long as OEM. check to see if magnaflow makes a catalytic converter for your car
