Unfortunately I haven't done anything to fix it. So here we go one more time.
Chris, I definitley agree that the catylic converter on bank 1 (passenger side) is bad. I reset the code and it came back within one hour. Also, the car has a rattling sound that has been verified that it is coming from that same catalytic converter. It definitley needs to get changed.
I'm writing to ask for advice on how to proceed. Chris, I read in your post that I should look into replacing the Y pipe assembly but I'm a little short on cash and I don't want to spend that much cash on this repair as I'm sure that I won't be driving this car within a year. Family got bigger and we need something bigger so more than likely I will be trading this in or selling it. With that said, can I just replace both CATS with universals. If so, will that be enough to clear my p-0420 code.
I ask cause I've been calling around getting quotes on replacing the cats only with universals. Talked with one muffler shop and was told that replacing the cats with universals was not the right way to fix it. Something about flow, blah, blah and that replacing only the cats might not clear the code. Was told by that shop that they will not guarantee from the code coming back going this route. Not sure if this was a bunch of BS in hopes of getting me to replace the Y pipe assembly for $700.
Advice / suggestions are always welcome.
