Um lets see if i can explain i really dont know the names of the componenet my boy cleaned. but its on the throttle body. I have an LS swap so its right under the throttle body basiccaly all we did was pull out the three bolts that hold the part in and then loosened it all the way out and cleaned it with some break cleaner and reinstalled it . what was happening on mine wa that the screw had back all the way out and was causeing the engine to surge so once we retightened it it stopped all together. i know its kind of a scketchy explanation but i dont remember the names of the parts and if u have an H22 I know that its a little different ill see if i can find some pics or something so i can explain it better to u later.
