Stalling Suzuki Ciaz Needs EVAP System Fix

Had similar issues with a 2013 Suzuki Swift with the check engine light and stalling. The symptoms pointed to a failing EVAP system, specifically clogged ventilation hoses and a stuck purge valve. The pressure sensor was reporting incorrect readings due to blockages in the system. The main problem was carbon buildup in the ventilation lines between the fuel tank and EVAP canister. This prevented proper fuel tank ventilation and vapor management. A thorough cleaning of the entire EVAP system was required, including replacement of the purge valve and pressure sensor. The job took about 4 hours at the shop. This is considered a moderate to serious repair since a malfunctioning EVAP system can lead to: Increased emissions, Poor fuel economy, Risk of fuel tank damage, Continued stalling issues, Failed emissions tests The repair should be done properly by a qualified technician who can perform complete diagnostic testing of the EVAP system. A poor repair job will likely mean the symptoms return within weeks. Consider finding a shop that specializes in fuel system repairs rather than returning to the previous mechanic. They should be able to properly test the system pressure and verify the repair fixed all issues.

Thanks for sharing that detailed breakdown of the EVAP system repair. Your fuel tank ventilation issues sound exactly like what I experienced. The emission system problems really are a headache when not fixed properly. Just curious, do you remember roughly how much you paid for the complete repair? Also, has your engine light stayed off since getting it fixed? I want to make sure I budget correctly and find a shop that will do the job right the first time. My gas cap is actually quite worn too, so I might have them check that while they are at it since it could be contributing to the pressure issues.

Just wanted to update you on the costs and results of my Suzuki Swift repair. The automotive repair shop charged 175€ to thoroughly clean the clogged hoses and inspect the entire emission system. The price included labor and replacement of a few small parts. The engine light has stayed completely off since the repair two months ago. The purge valve is working perfectly now, and the stalling issues are gone. A proper fix of the tank ventilation system really made all the difference. Getting the gas cap checked is definitely smart thinking. A faulty gas cap can trigger the engine light and cause similar pressure-related problems. Most shops will test it as part of their diagnostic process. The key was finding a shop that specializes in EVAP system repairs. They identified the exact issue with proper diagnostic equipment rather than just guessing at the problem.

I finally took my car to get fixed at a certified repair shop that specializes in emission systems. The total repair came to 220€, which included a full EVAP system cleaning, new purge valve, and they even replaced my worn gas cap at no extra charge. The technician showed me the clogged ventilation lines they removed from near the fuel tank, they were completely blocked with carbon deposits. No wonder my check engine light kept coming on. The whole repair took about 3 hours and they thoroughly tested the system afterward. Its been running perfectly for the past week with no check engine warnings or stalling. The idle is smooth again and fuel economy has improved. Really glad I found a shop that knew exactly what they were doing with the tank ventilation system. The extra cost was worth it for a proper fix rather than going back to the previous mechanic who clearly missed these issues.
