My '90 Integra has a warm water line going to the throttle body. Then from the TB, it goes back toward the fire wall, but I can't tell or see where it goes and what else it does. Anybody know about this system.

If I go with a higher flow throttle body, they don't have any water connection. I'd like to plug this line where it comes off the flange at the engine, but I don't know what else it goes to behind the engine.

Thanks!
