Citan engine issues and injector replacement

Have you scanned the vehicle for diagnostic trouble codes? I encountered similar performance degradation with a Citan, although I must emphasize the importance of proper diagnostic procedures. Fuel trim values and injector circuit resistance should be evaluated prior to component replacement. Clogging can be a factor, particularly if maintenance schedules have not been adhered to meticulously.

Codes were scanned, pointing to misfires and lean conditions. Fuel trims are definitely out of whack. Resistance checks on the injectors seemed normal, though. You think I'm missing something before I go for a replacement?

Given the data you present, proceeding with injector replacement is a reasonable course of action. However, I strongly advise a thorough inspection of the fuel supply system, including but not limited to the fuel filter, fuel pump, and fuel pressure regulator, to preclude recurrence of the issue. Consider engaging a qualified workshop to perform a comprehensive assessment. It is imperative to ensure proper functionality following replacement.

Thanks for the confirmation. Bit the bullet and had the injector replaced. Cost me 515€. Seems to have sorted it. Engine runs smooth as butter now and fuel consumption is back to normal. Lesson learned: Clogging can wreak havoc. Will keep an eye on the fuel system from now on.
