2 bolts to remove it, then 2 to break it in half. Take sensor safe cleaner and spray the heck out of it using a white cloth until it is all clean. I'm not sure what the electrical connection to the airbox is (by the IAC hose)but I unplugged it and removed the sensor in the airbox and wiped that with a dry cotton cloth.
Then remove intake hoses and prop open TB butterfly and spray all around there. Make sure ridges of carbon haven't built up not letting the TB snap shut. I even used a toothbrush to get around the edges.
Then resynch the cables following multiple previous posts. Works great!
