11-13 in the playoffs, and if you remember, the year the Colts won the Super Bowl and the Colts won 4 games in a row with Manning, he threw 2 TDs and 5 INTs in those 4 games.
So basically, the only successful playoff trip for Manning was a year in which the defense absolutely carried his atrocious play and he lucked out and got to face Rex Grossman (and his baby hands trying to throw a wet football) in the Super Bowl.
Manning is the greatest regular season QB in NFL history. Unfortunately, it ends there. This guy is putrid in the playoffs.
