- Merc 5.7 's Alpha Gen II Drives
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 still have same problem. All ICV's work fine with other engine. Any thoughts ?
Thanks
