    General Questoin

    I purchased my 97 deville on may 29,2004. Soon after that the service engine soon light came on. At first it was misfiring plugs. Then after I passed emissions it was misfiring plugs AND a PO441 error. They had my car more than a week fixing it at one point so I really have even had it a month. What can I do about this? I dont feel that I should be shelling out hundreds of dollars for repair on a car that I just bought. They have a 30 day policy at the used car lot(not a caddy lot) where they will repair anything. Can anyone give me advice on what to do? The car runs fine its just that I get those damn annoying codes. Please help

    P0441 - Evaporative Emission Control System Incorrect Purge Flow
    Is your gas cap tight? Is it the correct one? Are the hoses correctly connected to the EVAP canister, EVAP purge solenoid and EVAP vacuum control switch? Are the electrical connections good to the EVAP purge solenoid and EVAP vacuum control switch? (located on the right bank cam cover next to the coil pack)
