Coolant leaking somewhere around thermostat housing or intake. on 2003 Ford Explorer Sport Trac

Can see coolant leaking from what looks to be left of thermostat housing. Have check engine light and rough idle after engine warms up. Sometimes dies at idle. I was just going to replace thermostat when i saw the coolant coming from described area. Stopped until i find what other problems could potentially be. I have to use daily and was wondering if this a diy project in one day or extended expensive repair.
