Moco rough running exhaust leak

My 2014 Nissan Moco with a gasoline engine is running rough. The check engine light is on, and there's a code stored. It jerks when I accelerate, and it's driven 86465 km. Could it be fuel injectors, air filter, spark plugs, or the oxygen sensor? Any ideas?

I had something similar happen with my Moco a while back. Did you check for any leaks in the exhaust system? That was my problem, and it caused similar symptoms.

A leak in the exhaust system? How did you figure that out? Was it obvious, or did you need special equipment?

It wasn't obvious at first. The mechanic used some kind of smoke test to find it. I'd suggest getting it checked out at a workshop. Better safe than sorry!

Thanks so much! I took it to my local shop, and you were spot on – it was a small exhaust leak! Repair cost me 265€. I really appreciate the help!
