Exhaust Smelling like ammonia in 2006 Honda Pilot

I have a Honda Pilot 2006. For a while, the exhaust has been giving off this smell (kind of like ammonia). It only happens after a cold start and disappears after couple of minutes. I want to know if it’s something serious.

 

Thank you for your time.

Have you switched to a different gas station recently? Is your cat all good?


I have been going to the same gas station for years. As far as catalytic converter, I am not sure. I recently had emission inspection done, and nothing was an issue.


Unless some sick person is playing a prank on you, try buying fuel from a different brand for a few weeks & check if the smell still persists.
