Don't clean the coating off the outside. Just use some carb cleaner on the inside...
The easiest way to find it..is it's what the plastic air intake tubes are mounted to under that black cover ontop of the engine.

Careful on using carb cleaner. Some of the throttle bodies (like mine) have a special coating on the inside that the carb cleaner strips off (you'll see a sticker on the throttle body saying "do not clean" or something like that - don't worry about it though). I'd recomend getting a throttle body cleaner - it's supposedly safe for the coatings. As Mustang said, you just take off the intake tubes and spray the inside as per the directions.

The "special coating" is on the inside. Carb cleaner will take it off. You can use special throttle body cleaner that won't remove it if you want. But since that coating didn't prevent the TB from getting dirty, IMO it's probably not a big deal if it was removed as long as you keep it clean in the future.
Dang Gregg, we posted at the same time and they say pretty much the same thing.

Be careful when you clean the Throttle Body, and replace the gasket before you put it back on, dont forget that step, when the throttle body is back on, but not completely, start the engine, and spray air intake cleaner while it is running, it will bog down, but it will clean it.
