Use THROTTLE BODY cleaner. Most cars have a teflon or similar coating inside metal intake parts. Carb and break clean will take it right off and it will start to pit like a son of a bitch. I found this out when I cleaned the IAC and throttle body in my Ranger. Had to buy a new throttle body and IAC. The butter fly in my throttle body seized up and the IAC seized also. Better safe then sorry.
