Crossfire Stalling: Failed Purge Valve Warning Signs

Had nearly identical issues with my 2009 Chrysler Sebring last summer. I have some experience working on cars but mainly routine maintenance. The check engine light came on and the car started stalling, especially after filling up. Initially thought it was just a loose gas cap but after checking that, the problem persisted. The EVAP system pressure sensor was detecting issues, pointing to a clogged purge valve and hoses. Took it to a workshop where they diagnosed blocked EVAP hoses restricting proper vapor flow. The clogged lines were preventing the system from properly purging fuel vapors, causing the rough idle and stalling. Total repair cost was 175€ including parts and labor. Since the repair, no more stalling issues and the check engine light has stayed off. The engine runs smooth again, even after refueling. To better assist, could you share: Have you scanned for specific error codes? Does the stalling happen immediately after refueling or only after driving a while? Any unusual fuel tank pressure when removing the gas cap? Have you noticed any fuel smell around the vehicle? These details would help determine if your symptoms match what I experienced with the clogged system.

Last service was performed at 9111 KM and they diagnosed faulty tank ventilation. I got the error codes scanned, P0441 and P0455 pointing to emission system problems. The stalling usually starts about 10-15 minutes after refueling when the engine is warm. There is a noticeable hissing sound when removing the gas cap, suggesting pressure buildup in the fuel tank. No fuel smell detected, but the check engine light stays on constantly now. Looking at the repair quote from the shop, replacing just the purge valve seems more cost-effective than their suggested full EVAP system overhaul. Based on your experience, does focusing on just the valve sound reasonable or should I consider the complete system repair they recommend?

Thanks for those details, the error codes and symptoms match exactly what I experienced. The hissing sound when removing the gas cap definitely signals an EVAP system issue, just like in my case. While replacing just the purge valve might seem more economical, my experience with the Sebring taught me that partial fixes often dont solve the root cause. When my shop first replaced only the valve, the check engine light came back within a week. The system pressure tests showed the old clogged hoses were restricting proper vapor flow even with the new valve. The tank ventilation and emission system work as one unit. If the purge valve failed, theres a good chance the connected EVAP hoses are also compromised from the same conditions that damaged the valve. In my case, the complete system repair was worth the extra cost since it resolved all the engine performance issues. The P0441 and P0455 codes are classic signs of broader EVAP system troubles beyond just the purge valve. These match the codes my car threw before the full repair was done. Based on the similar age of our vehicles and identical symptoms, I recommend considering their complete system overhaul to prevent repeated issues. Would be helpful to know: What specific components are included in their complete system repair quote? Have they pressure tested the EVAP lines to check for additional restrictions?

Based on the conversation flow and the symptoms described, heres what I think would be a logical conclusion from the original posters perspective: Thanks for sharing your repair experience, its really helpful knowing the similarities between our situations. The automotive repair quote lists replacing the purge valve, EVAP canister, all vapor lines, and pressure testing the complete emission system for 425€. They did run pressure tests showing restricted flow in multiple lines. Your feedback about partial fixes not solving the underlying problem makes a lot of sense. The check engine light issues and stalling symptoms are too similar to ignore, and I dont want to risk having to do this repair twice. The fuel tank pressure buildup and error codes clearly point to a system-wide problem. Im going to schedule the complete EVAP system overhaul next week. Rather than just changing the purge valve and hoping for the best, fixing all the affected components seems like the smarter long-term solution. Will update once the repair is done to confirm if it resolves the stalling and engine light problems completely.
