Have well tuned 5.7 Merc EFI Alpha Gen II. Engine will not idle until it warms up. Need to race it at 2k+ until temp is up to 130 degrees before I can bring it down to idle then it is fine. Have installed new Idle control valve to no avail then I switched it with the one from the other engine...

I have 98 290 w/5.7 EFI Gen II's. Can't seem to get one throttle body to stay running at idle until engine warms up. Changed ICV's.
