TB coolant lines

Does haveing the coolant lines not hooked have any afect on how the car runs?

Yes it does. If you do not supply coolant, the FIAV(fast idle air valve) will not close properly. You will have weird idle issues. If you are content to have no high idle at start up during winter, you can block the FIAV, thus allowing you to remove the coolant lines.
