    2004 STX12F and 2009 STX15F Throttle body interchangable?

    Was wondering if it was possible to put a 2009 STX15F throttle Body onto a 2004 STX12F?

    They look a little different but seem to use the same housing for mounting.

    Having Idle issues with my 04 STX12F and there is a guy parting out a low hour 2009 STX15F near me.

    No, they are totally different size bores.

    The older I get, the more I find myself fixing things that I knew I was doing correctly at the time.

    Sounds like the idle speed control,does it stall when you let off the throttle? Is it hard to start?

    Yes I have to kick it over for like 45 seconds straight to get it to start up when cold. When warm it starts fine

    Isc will stall when you let off the throttle,if it's not stalling check your fuel filter or fuel pump screen.

    Fuel filter and screen inside the gas tank?

    fuel filter on 2004 should be in front of engige ,just look for the fuel lines from the fuel injector rail,try that fuel filter first,remove it and blow it out,if its rusty replace it.it that's not the problem,you have to check the fuel pump screen,. easiest way is to remove glove box and you can pull fuel pump right out from there.clean the screen,and check inside the tank.you may have to drain the tank if there is anyting in the bottom.
