Why the eff is the inside of my throttle body black? it almost looks like dirt, grime, and oil. ive only had this car for about a year. i bought it used and havnt looked inside the throttle body before. But, its horrible. What should i use to clean it? Ill be taking it off but ive heard theres some stuff you cant use to clean them.

 

Its not abnormal so dont worry. I would however check the pcv valve if its real wet. if u go get some throttle body cleaner at ur local parts store. take a rag rap it around the end of a decent length screwdriver. soak the rag with cleaner and start cleaning. dont forget to open the butterfly valve and get behind there as well. i know the instructions say spray it directly in. however i work on old v-8's alot and its not good for the internals. Also, Gunk makes the best cleaner in my opinion.
