Cronos Injection Nozzle Issue
Summary of the thread
A Fiat Cronos 2023 with high mileage exhibited rough starting, high fuel consumption, reduced power, uneven idle, and stalling. The suspected cause was a dirty or clogged injection nozzle. After professional inspection, it was confirmed that the injection nozzle was defective, leading to the replacement of all injectors, which resolved the issues.

No codes, fuel filter is new. Clogging seems most likely. Did you have to replace the injectors in your Peugeot, or was cleaning enough?

Cleaning didn't cut it; needed replacement. Given your mileage, might be the same. Best to get it checked professionally. Injection nozzles defective is no joke.

Yep, you were spot on. Took it to a shop; confirmed, injection nozzle defective. Replaced all injectors. Cost 515€. Runs like new now. Thanks!

Sounds familiar. Had similar symptoms with my old Peugeot – turned out to be injector clogging. Have you checked for error codes? Could also be fuel filter.
