Getting a 2 amp draw on my TBC fuse after the truck is off . Kills battery n a couple hours. Truck runs fine and smooth. Should I change the throttle body ??

 

Is that the only thing on that circuit? Make sure you don't have a bare spot on any of the ire insulation. If you have an ohm meter, check the pin out to ground, and across each other. If that all checks good, that's what I would do, change it out.
