Hey guys I have had this check engine light on for awhile now, last inspection time I just dumped a bottle of sea foam in and light cleared, passed inspection and as I pulled away it turned on. Well it’s time again, and it’s showing the right bank cat is bad which has always been the problem with this check engine code, and I just want to fix it and be done with it. I went to a shop and to get a new one plus labor it’s about 1100 bucks. I called pep boys and they said I should just find a cat and take it to a muffler shop and have them weld it in. Any one in here run into this issue? If so what did you do? I looked on eBayand they sell a pair that’s from the intake back with a new cat for around 250-275 and I’m sure the muffler shop would be around 30-40 bucks or so. That 1100 dollar quote was just to fix and replace the bank 2 cat. To fix each side it would then be double, as they always try and say well if you fix one you should fix both just incase. Idk if I can just buy the pair off eBay and get them welded in, and it would work then I’m game for that, and saving some cash.![]()

Right ... P0340 shouldn't be a cat problem. I can't say anything more specific because kawiman hasn't bothered to give us the specifics on his Taco (year; model; engine; tranny ...).... Just as a side note, p0340 is not a cat code, either p0420 or p0421 would be, are you sure its the cat that has gone bad?
