I recently had my check engine light come on, but then after a few days it went off, now it is back on. So, I took it to Advance Auto Parts and used their diagnostic testing machine and it came back as Emissions Control System Leak EVAP(Large)...Does that mean I possibly might just have to replace the gas cap or is it somewhere in the hoses or the vacuum itself? If anyone could help, please do so thanks!
