GTA 4 uses a pretty broken p2p matchmaking system and you should not expect in any way to receive a fraction of the quality you receive with the also flawed MW2 p2p Matchmaking. And it does not allow for joining in progress so that just won't happen unless it's free mode. Also the population of people playing this game online is not very big and with the vast amount of game types in the game it is likely that a lot of game types are virtually vacant. Free Mode being the most popular is likely to be your best bet in terms of playing GTA multiplayer. Also, you should experiment with other game types to see if there are any other popular modes. I for one have been somewhat successful with the race game mode although I have not been on so this may no longer be the case.
