Thanks for your thoughts. I started the eng late last night in my driveway and it took two tries to get it started and stumbled when I stepped on the gas until it warmed up. This maybe a separate issue but thought I would mention it incase there was a connection. I let it sit over night and tested it this morning and the anti freeze looked clear. I ran it with the heater off so I am thinking it may have been something in the heater core that floated to the top of the radiator that gave a cloudy appearance. I will run it again with the heater on to see if the cloudy stuff comes back. I have never seen this before so it still is a mystery to me.
