Engine running and performance problems with Fiat Doblo
(Translated from German)
Summary of the thread
A 2004 Fiat Doblo is experiencing rough engine running, reduced power, delayed cold starts, and idling shudders. Possible causes include a clogged fuel filter, injector issues, or vacuum leaks. Suggested solutions involve checking and replacing the fuel filter, ensuring the diagnostic tool's compatibility for injector coding, and inspecting for vacuum leaks in the intake system. If injector coding is needed, professional testing or cleaning is recommended, and further support may be required for coding compatibility.

Start by checking the fuel filter for any clogs or dirt, as a blocked filter can cause rough running and reduced power. Replace it if necessary. Let us know if this resolves the issue or if you need further assistance.
The codes of the injectors are not displayed, other testers are also connected. Now the question arises, can I code them with Carly?

hello
If the injector codes are not displaying, it might be an issue with the diagnostic tool or the vehicle's ECU. Before attempting to code the injectors, ensure that the diagnostic tool is compatible with your vehicle. If you suspect injector issues, consider having them tested or cleaned professionally. Let us know if you need further guidance or have any questions.

Check for any vacuum leaks in the intake system, as these can cause rough idling and reduced engine performance. Inspect hoses and connections for any signs of wear or damage. Let us know if this helps or if you have further questions.
