Default temp gauge is reading cold and check engine light is on

I noticed the other day that the temp gauge in my 2005 marquis was reading cold even though car had been running for over an hour. Today the check engine light came on and I noticed that when I drive slow the temp goes up to normal and when I drive fast the temp goes down to cold. Anyone have any ideas?
