Citroen Xsara rough idle and stalling

I'm at my wit's end! I've got a 2002 Citroen Xsara, gasoline engine, with 114170 km on the clock, and it's throwing a fit. The check engine light is on, the engine runs rough, stalls when idling, and jerks when I accelerate. I suspect it's the fuel pump. Could it be? What do you think?

I once had similar issues with a 2011 Opel Astra. Before replacing expensive parts, did you check the fuel pressure sensor? What about its cable or plug connection?

The fuel pressure sensor, you say? I hadn't considered that. Where exactly is that located, and what should I be looking for? Is it a common issue?

The sensor is usually located on the fuel rail. In my case, it was indeed the connector causing the issue, resulting in similar symptoms. But I would still suggest checking the sensor itself. If you are not comfortable doing it yourself, I recommend visiting your local workshop.

You were spot on! Took it to the shop, and it turned out to be a defective fuel pressure sensor. The cable and plug connection were indeed faulty. 95€ later, and she's running like a dream again. Thanks for pointing me in the right direction!
