well, first off im new to this site..and the problem im having with my 04 honda civic si hatch is that my idle bounces from 900 to a little above 2k rpm and after about 5 to 10 minutes with the car running, it'll start bouncing like it's red lining at 2k rpm..im thinking it's my idle air control valve..but im new to the newer year hondas..well, can anyone help me out..and if it is my iacvalve then where is it located, and what are the procedures that i have to do to take it out and clean it??? lmk thanks
