2002 KJ a few days ago idle would stumble when KJ was cold. I would pull up to stop sign and apply brake idle would drop to 300 or 400 rpm. I could not figure out the connection between applying brake and idle stumble. After KJ was warm problem would go away. Any thoughts are appreciated. |

Ever had the tranny flushed? Sounds like the torque converter having issues, to me. |

never had a flush but dropped pan and changed filter. I know that this method leaves old fluid in converter but never had any tranny issues before thanks for the imput. |

I had the same thing happen to me last Saturday. When I came to a stop the engine died. Started happening when it was 23 out. Cleaned the throttle body out like the post said, added some fuel injector cleaner and the KJ's running like a scalded something or another  As usual, this site saves me bucks
