I have a 2004 Subaru Legacy with 49,500 miles on it and lately the check engine light has been coming on after I fill up with fuel. It stays on for a few days then goes off. This has been going on for the past few fill ups. There is no loss of power and the car runs great. Please help! Thanks.

Hi there,

The tank purge system may be acting up, get the code scanned and report back your findings.
