Trafic rough running

It could be related to the fuel system. Given the symptoms, a defective fuel pressure sensor is a possibility. Have you noticed any change in your fuel economy recently? Also, any unusual smells from the exhaust?

Thanks for the reply. I haven't really paid close attention to the fuel economy, to be honest. As for smells, nothing out of the ordinary that I've noticed. Where exactly is the fuel pressure sensor located? Is it something I could check myself, like a loose wire or something?

The fuel pressure sensor is typically located on the fuel rail. It's possible a cable or plug connection is defective. However, given your expertise level and the potential for fuel leaks, I would suggest having a workshop diagnose the issue. They can properly test the sensor and fuel system.

Thanks, I appreciate the advice. Took it to a local garage, and you were spot on - it was the fuel pressure sensor. Apparently, a wire was loose. They replaced the sensor and fixed the connection. Total cost was 95€. Runs like a charm now!
