I know this is no new subject and in fact has been discussed countless times. But I'm hoping to get some advice on a reliable fix without having to spend nearly a grand for new factory CAT.
My P0430 Bank 2 code first appeared about 8 years ago, so I replaced it with either a Magnaflow or Flowmaster (I forgot already) system, it went away for almost a year then came back, then O2 sensors were replaced (forgot which ones), that was good for about another year. Then the same code started coming up about +/-5 years ago and has been ever since. Car idles fine, no noticeable performance issues or any other sounds or anything at all other then the three lights (engine, trac, and VSC) that typically come up.
I recall I've read somewhere there could be a fix that deals with the O2 sensors. Do I really need to get another aftermarket CAT? Do I replace all four O2 sensors? I also tried additives as well.
Any advice would be appreciated. I've been using OBD II to erase the code until I'm so tired of this and just let it go out on its own but that's random, could be weeks or months, you never know.
