Does that sound right?
Weber looks for 850 - 900 rpm and raises it if it sees it lower or requires it due to coolant temperature. If you set it to 900rpm when hot and then plug in the ISCV and it changes, something isnt quite right.
Contrary to popular belief - The ISCV is NOT there to control idle speed.
