Dodge Journey Diesel: Critical Misfire Troubleshooting

After working on several cars myself, I had a very similar issue with my 2013 Dodge Durango diesel. The symptoms you describe match exactly what I experienced, engine misfiring, rough idle, and the check engine light constantly illuminated. After diagnosing the problem, it turned out to be a faulty fuel injector causing combustion misfire. The repair involved replacing the defective injection valve, which resolved the jerking during acceleration and restored normal power output. The total cost was 515€ for parts and labor. Before jumping to conclusions though, it would help to know: Have you scanned for error codes? How many kilometers/miles are on your Journey? When was the last fuel system maintenance performed? Are these symptoms constant or do they vary with engine temperature? Have you noticed any unusual fuel consumption? Since this could also be related to other components like the fuel pump or spark plugs, having this information would help narrow down the exact cause. If you can share these details, I can provide more specific guidance based on my experience with the repair process. What helped me most was having a professional diagnostic scan done first, this pinpointed the specific injector that was malfunctioning and saved time in the repair process.

Thanks for the feedback. Yes, my Journey has 58818 KM on the odometer and just had its service last month. The rough idle and engine misfiring started shortly after. The scan showed P0201 and P0202 codes, pointing to injection circuit issues. The throttle response definitely gets worse when the engine is cold, and fuel consumption has increased by about 15% in the past weeks. The symptoms are pretty consistent, the engine misfiring is most noticeable at low RPMs and during initial acceleration. I checked my maintenance records and the fuel pump was actually replaced about 40000 KM ago. The current issues feel similar to what you described with your Durango, especially the power loss during acceleration. Would you recommend going straight for the injector replacement rather than trying a fuel system cleaning first?

Thanks for those additional details. Based on those P0201 and P0202 codes and your symptoms, this definitely mirrors what I encountered with my Durango. While fuel system cleaning might help in some cases, the specific error codes and similarity to my experience strongly suggest faulty injectors. The cold start issues and increased fuel consumption you mentioned were exactly what I experienced before replacing my injectors. The combustion misfire was most evident during cold starts and low RPM situations, just like youre describing. In my case, trying fuel system cleaning first actually just delayed the inevitable and cost extra money. With those specific error codes pointing to injection circuit problems, I would recommend going straight for injector replacement. This is especially true since your fuel pump is relatively new at 40000 KM. The check engine light should clear up right after replacement, and you should notice immediate improvement in: Throttle response, Fuel efficiency, Engine smoothness at idle, Power delivery during acceleration The repair cost might vary, but based on my experience, budget around 500-600€ for parts and labor to replace the affected injectors. Its worth getting this addressed soon, as continued misfiring can potentially cause additional engine damage over time.

Thanks for the thorough info. After hearing about your experience with the Durango, I feel more confident about the direction I need to take. The symptom match is spot on, especially the cold start issues and power loss during acceleration. Those error codes combined with the rough idle and engine misfiring make it clear that injector replacement is the best path forward. You saved me time and money by helping me avoid the fuel system cleaning step. Since the fuel pump is relatively new and the combustion misfire symptoms match your case so closely, I will schedule the injector replacement this week. Really helpful to have a cost estimate of 500-600€ for the repair. Having dealt with the same issue successfully in your Durango makes me feel better about tackling this problem. Will make sure to get it done soon to prevent any additional engine damage from the continuous misfiring. I will update once the repair is complete. Thanks again for sharing your experience, it was exactly what I needed to confirm my suspicions about the injectors being the root cause.
