Code goes on for a week and off for a week, I took it to
the shop and they said I had a bad gasket that
connects the converter to the muffler,they fixed it but
light is back on...help!!!
you could have a bad 02 sensor at the CAT or your CAT is bad. Cats don't usually connect to the mufflers, but if the gasket was leaking at the CAT it could have damaged the CAT.
