The throttle body on most cars I've seen is fairly simple to remove. You'll need a socket set, and some spanners, and a couple of new gaskets.

First things first, remove the cables (up to 3) from the throttle opener. They should just unclip. Place the ends aside, remembering where they came from. Remove any hoses and wires connected to the body, being careful to label them so they go back to the right spot. Remove any brackets and mounts around the throttle body that get in your way. Unscrew the bolts holding the throttle body to the inlet manifold, then remove. Remove all traces of the old gasket from the inlet manifold.
