Foam in water after de-winterizing

For some reason I'm getting foam from the kitchen sink on the cold water, bathroom faucet seems normal. I never put the water filter back in, could that be causing this?

Did you put anti-freeze in the fresh-water tank?
If so, you will get the foam (and taste and smell) for a LONG time!
If you did not, just run your water and it will clear fairly quickly.
