I cleaned my throttle body yesterday on my 02 Trailblazer LT. Took it off, sprayed some CRC TB cleaner on a rag and got her spotless. While looking at it, I noticed that the nipple on the right that has the plug that you have to depress to get off was a tad dirty on the inside but I wasn't sure I could shoot some spray in there or not so I didn't. So my question is now, should I have tried to clean that out or is it fine with a slight coating of gunk? Thanks.
