I took my 2007 V50 to the auto zone and had them hook up the computer because the check engine light came on. all 5 cylinders were misfiring because the system was too lean and it said large vacuum leak. The guy said that the most likely cause of the fuel system being too lean was a fuel filter that needs replacing. He said that he didnt have any idea about the vacuum leak. anyone with experience with these cars have any experience with these problems? as far as running too lean I figured maybe a new fuel filter and maybe new injectors but honestly i dont know enough to be guessing like that.
