Summary of the thread
A 2017 Citroen C4 is experiencing poor starting, increased fuel consumption, power loss, uneven idling, and occasional stalling. The suspected causes include a defective injection nozzle or a dirty valve. It is suggested to have the injection system professionally checked, as a clogged injector or bad spray pattern could be the issue. A professional diagnosis and potential replacement of the nozzle are recommended for resolution.

Thanks. How did you check the spray pattern on your Opel? Did you remove the injectors yourself, or did a professional examine them? Trying to figure out the best way to handle this without making things worse.

I didn't check it myself. I took it to a workshop because of the potential for damage and the need for special tools. They confirmed the spray pattern issue and recommended replacement. Getting a professional diagnosis is probably best.

Understood. I'll schedule an appointment with a trusted workshop to have the injection system checked. They quoted about 515€ for the repair, including replacing the nozzle. Thanks for sharing your experience; it helped me decide.

I had similar issues with my Opel Astra, but it's a diesel. Poor starting, rough idle, and power loss. One of the injectors was clogged. Have you checked the spray pattern of your injectors? A bad pattern can cause those symptoms.
