    Question Engine noise/throttle body

    Hey guys just bought a SS inductions 78mm throttle body and fitted it. I found out that colant ran through the bottom of my orginal one and have bypassed that. Looking on the forums i have seen that people say its just to prevent it sticking with freezing but just wanted to ask as not 100% sure.
    I found my old throttle body the control flap in the middle one of the star screws was loose and the control flap could move around, hopping this is what was causing my accelerater to stick after hard acceleration (or as it was more frequently, burnouts :P)
    I have also found that a tapping/nocking noise comming from my engin bay has stoped, maby it was the losse control flap in the old throttle body?
    The other thing i wanted to say was that in my stock throttle body when i pulled of the colant it came out with a fair amount of pressure, posible that hadent let car sit for long enough but i noticed that the first 2-3 seconds of discharge was dirty/rusty looking and that the metal conection on the bottom of the stock throttle body was cloged with rust. I tryed to blow through it and it woulnt budge!
    I just thought it was worth mentioning, any info would be nice.
    Thanks Toby.

    Why did coolant run through it,the throttle body is part of the air intake,air should run through it not coolant

    It dosent run through the throttle body as such, it runs through a conection bilt into the bottom of it, rang mechanic and asked and he confermed its to stop it freezing shut in cold climates
