    My 2015 Tahoe is throwing a check engine light, with the code P050D meaning "Cold start, rough idle" and every so often it also has code P0303 meaning " Cylinder 3 misfire detected".
    Has anyone else had these errors, know anything about them, or had them repaired? I'm thinking about taking it to the dealer but would like to know what I'm getting into.

    Thanks.
