Hello to all - I have an '06 CTS with the 6 cylinder motor, and today I threw a P0430 MIL. I read somewhere in this forum that the exhaust system is warranteed for 80,000 miles by Cadillac. Is that just for the original owner? My car has 74,000 miles on it and I bought it used. I will add that I recently replaced the #2 coil, and only drove the car for about 50 miles before I got it fixed. I know a misfiring cylinder can damage a cat, but do you think 50 miles would really hurt it? Last question- Bank 2 - which cat is that? Thanks in advance for the help. BTW - I cancelled the code, but I am sure that it will eventually come back on, and while the car is running fine now, I want it to be right so as not to do any further damage.
