Do I need to keep the heater lines and the coolant lines that run to the throttle body? Does the sensor on the throttle body still act normal if there were no coolant lines hooked to it. Seems like they would only be there for cold start and then after that it would be a waste an I correct? As long as I dont care about having a heater in the car cant I just by pass the heater core lines and get all the lins off the intake?
