Hello all,

After cleaning out the ICV, I saw a slight RPM increase at idle. Spraying carb. cleaner on the suspected parts, I found that the leak occurs at the bottom lip of the large round rubber thingy as pointed out in the attached picture (idle raises as I spray to the lip). What's this rubber thing & is there a easy replacement for it ?

Thanks,
Frank.
