Cleaning throttle body?

[richards72chevy]

Thanks GM-power.I ended up having to cut off the line on the drivers side.Tried calling all the parts stores even the chevy dealer ship none of them had that hose.I got some fuel injection hose on there.Hope it holds up to the heat and the coolant.The throttle body was very dirty I doubt it has ever been taken off and cleaned.Seems to idle and run a little better.Hope it turns off the check engine lite.Does any body know if that fuel injection hose will hold up in the heat and coolant?
