Okay guys/girls!!! I replaced my CAT a month ago because my stock one was gone. It was setting off an engine code and I was getting that weird smell in the cabin. I went to a muffler place and he was able to get an aftermarket one on there. Now a month later the engine code is back which means I need another CAT. Any ideas? Is it because I went aftermarket? Do you think something could be leaking internally??

Most aftermarket cats will still throw codes.It dosnet mean anything is wrong just the pcm reading the o2 sensors report.Your cat is flowing too good thats all.Is it magnaflow?

google the spark plug no fouler trick for your 02 sensor then do that.
12-24-2010
Yeah its Magna Flow!!! I will look up that spark plug fouler trick!

i had a magnaflow cat and my ses light stayed on about a month then finally deleted code and never came back.
