Got a question. I recently picked up a stock '95 GT throttle body to use on my 2.3L Turbo. I noticed the TB has a sticker on it that says "Do not clean inside throttle body-special coating on throttle blade and bore." What's the deal with this? The bore of this throttle body is covered with gunk so I'd like to clean it, but I don't wanna screw something up
