2008 CM871 Smelly exhaust and surge

[HankAz]

Well I really can't describe it but it is a different smell of exhaust not rotten eggs not sweet like antifreeze. Seems like it makes this smell when it needs a regen. It's not doing either now the miss, studder or the smell. I don't know but thanks for all the fast input. That's what I like about this group of people. Throw out some thoughts and see what sticks.
