2002W163 Ml 320 exhaust rattle & check engine
Hello everyone,
I am experiencing some exhaust rattle which appears to be from under the passenger front area. Thr check engine light came on a couple days after. I have read that these cars have issues with cats. Is this a sign of the cat going bad ?
I pulled codes and it appears that both banks are running lean.
Any

help is appreciated
