My 2003 honda crv had it’s cat stolen in 2022. I got it replaced and almost exactly a year later the new cat starts making rattling noises and the computer is running an emissions system code. I get the cat replaced at the same shop and now almost exactly a year later again my cat is rattling.
What could be disintegrating my cats? Is it because my car is burning oil? I’m sick of paying for a new one every year.
I’d be wondering about the quality of the cats you installed.
How can I check?
do you have a receipt/part number/etc from when the cat was installed?
