Coolant lines to throttle body?
There are two coolant lines that go into the bottom of the throttle body on the h22a(one is in and one is out i guess). Does any one know what the purpous of these coolant lines are and if there are any benifets if you bypass them?

if you bypass, once your car heats up, it will idle irratically, up and down. for example, from 1000-1500 rpm. the tb uses the coolant to know when the car is up to operating temperature, so it adjusts to the warm engine.
