Citroen C5 poor starting and stalling

Hi, I've got a 2007 Citroen C5 gasoline engine with only 23666 km on the clock. Recently, it's been starting poorly, the fuel consumption seems higher, and the engine feels like it has reduced power. Sometimes it idles unevenly, and even stalls. Could a dirty injection nozzle be the issue? Any ideas?

A 2007 Citroen C5 with a gasoline engine was experiencing poor starting, increased fuel consumption, reduced power, uneven idling, and occasional stalling. The initial suspicion was a dirty injection nozzle, which could cause these symptoms. After consulting with a professional, the defective injection nozzle was confirmed and replaced, resolving the issues and restoring the car's performance.

Did this summary help you solve your problem?

Sounds plausible. A clogged injector could definitely cause those symptoms, especially with gasoline engines. Have you noticed any misfires or rough running at higher speeds? How’s the exhaust looking – any unusual smells or excessive smoke? Could be running lean.

Thanks for the quick reply! Misfires, yes, I think I've felt a few at higher speeds. I haven’t checked the exhaust closely, but I'll take a look. If it is a dirty injector, is there anything I can try myself, or is it best left to a professional?

Given the misfires and the stalling, it's probably best to get it checked out. You could try an injector cleaner additive, but it's a bit of a gamble. A workshop can properly diagnose it, rule out other possibilities, and clean or replace the injectors if needed. Expect to pay around 500€ for the repair though. Could also be related to emissions issues.

Appreciate the advice! I'll book it in at a workshop and get them to take a look. They confirmed that the injection nozzle was defective. It was replaced for 515€, and the car is now running smoothly again.
