coolant is H E L L on o2 sensors.. if you spilled a significant amount directly on one, it could render it useless..

that's a little bit of info worth sharing.. but, likely not your issue.. your issue is most likely that you have a vacuum leak...

get yourself a can of TB cleaner aerosol.. spray carefully around the firewall of the truck.. when you hear the idle change, you've found the area your leak.. of course, it could be an easy one, and you may simply see a hose dangling somewhere.. start at the manifold and work downstream..
