Peugeot 807 Uneven Running Resolved

My 2007 Peugeot 807 with a gasoline engine (261082 km) is running unevenly, jerking when I accelerate. The check engine light is on, and there's an error code. Could this be fuel injectors, the air filter, a misfire, or the oxygen sensor? The timing belt was recently replaced.

Possible causes considered included fuel injectors, air filter, misfire, or oxygen sensor issues. After checking, an exhaust leak near the manifold gasket was identified and repaired, resolving the uneven running problem.

I had a similar issue with my 807. Have you checked the exhaust system for leaks? It's a common problem.

Thanks! Can you tell me where the exhaust is likely to leak, and what other symptoms you had besides the rough running?

My leak was near the manifold gasket. Besides the rough running, the engine was louder. Check it thoroughly. If you don't have the tools, get a workshop to look at it.

I had the exhaust checked, and there was a leak. The repair was 265€. The uneven running is fixed. Thanks!
