    Rough idle on 09 WRX?

    My 2009 WRX with less than 1000 miles has rough idle right now. It feel almost like a bad motor mount. Any ideas?
    Thanks,
    Jim

    This your first Subie?

    They idle a little different when compared to most cars...

    Is your engine making a "knocking" sound? Some people have been having problems with he 09's having a turned rod bearing. there are examples on youtube if you need to compare.

    Sounds like mine. I believe yuor right that it's just the flat four doing its thing. It starts right up and seems to pull fine. Thanks for the help.
