Hey guys! First post of many to come. I own a 2004 imola sedan. With ~130k on the clock.
I'm having some issues tracking down the cause of the p0420 and p0430 codes. I've replaced the 02 sensors and put on lower mile cats.
I've searched around for quite some time trying to find out why, but about 99% of posts are for only one bank having codes. Never both at the same time. I was curious if anyone has any input or maybe knows why this would happen. It's very strange.
My car does consume a decent amount of oil, I am not sure if that could relate.
Thanks
